Try changing in your bootloader root=/dev/hdb1 to root=341

tried it already with 
	root=0341
and 
	root=341
on the lilo prompt. No change.

(Beside the kernel telling me:
	VFS: Cannot mount root fs "341" or "hdb1"

2.6.0-test3 cannot mount root fs

[Norbert Preining]

Hi friends!

I am trying 2.6.0-test3 but cannot get the kernel to mount /dev/hdb1
which is the root fs.

I tells me all the usual stuff concerning that it finds the controllers
(VIA and HPT) and disks/cdroms, but than hangs with
	cannot mount rootfs "NULL" or hdb1
I have compile in (of course) the filesystems of my root fs (ext3) and
everything else I thought may be necessary, or at least what has been
necessary up to 2.4.22-rc2.

hardware: athlon, via686 ide + hpt366/370 ide, linux is un hdb

here my config options for ide:
CONFIG_IDE=y
CONFIG_BLK_DEV_IDE=y
CONFIG_BLK_DEV_IDEDISK=y
CONFIG_IDEDISK_MULTI_MODE=y
CONFIG_IDEDISK_STROKE=y
CONFIG_BLK_DEV_IDECD=y
CONFIG_BLK_DEV_IDEFLOPPY=m
CONFIG_BLK_DEV_IDESCSI=m
CONFIG_IDE_TASKFILE_IO=y
CONFIG_BLK_DEV_IDEPCI=y
CONFIG_IDEPCI_SHARE_IRQ=y
CONFIG_BLK_DEV_IDEDMA_PCI=y
CONFIG_IDEDMA_PCI_AUTO=y
CONFIG_BLK_DEV_IDEDMA=y
CONFIG_IDEDMA_AUTO=y

for FS:
CONFIG_EXT2_FS=y
CONFIG_EXT3_FS=y
CONFIG_MINIX_FS=m
CONFIG_ROMFS_FS=m
CONFIG_ISO9660_FS=m
CONFIG_ZISOFS=y
CONFIG_ZISOFS_FS=m
CONFIG_UDF_FS=m
CONFIG_FAT_FS=y
CONFIG_MSDOS_FS=y
CONFIG_VFAT_FS=y
CONFIG_NTFS_FS=m
CONFIG_PROC_FS=y
CONFIG_DEVPTS_FS=y
CONFIG_TMPFS=y
CONFIG_RAMFS=y
CONFIG_HFS_FS=m
CONFIG_CRAMFS=m

Unfortunately I cannot capture the output of the boot of 2.6.0, but I
would happily compare it to one's dmesg output. So if you have 2.6.0
running with via686 can you send me the dmesg after boot, so that I can
check what there should be or what I  am missing.

Thanks a lot

Best wishes

Norbert

are you using devfs? if so, the devfs device name
would be apropriate root=/dev/ide/host0/bus0/target1/lun0/part1

how does the lilo config look like, and what kernel
command line is reported on boot ...

Did you patch up or install the full tree ? I had this problem 
when I patched 2.6.0-test1 -> 2.6.0-test2.

Rebuilding a fully downloaded source tree appears to have fixed
it for me in -test2. Will try -test3 now.

Justa stupid guess, but the format has been changed. Instead, try

root=03:41

Re: 2.6.0-test3 cannot mount root fs

[gaxt]

It's not a lilo issue (ie. I use grub) I ran into the issue when I first 
started with the 2.6.0 series test kernels.

DVD Problems 2.6.0-test3 & 2.6.0-test2-mm5

[gaxt]

DVDs play fine in 2.4.21 but will not play in 2.6.0-test2-mm5 or 
2.6.0-test3. With ogle, this is what spits out:

dave@localhost dave $ ogle

I tried several DVDs and three gave the above error and one worked but I 
suspect the working one had no copy-protection encoding (low budget 
release unlike the two others: Jeeves & Wooster and Blackadder and Dirty 
Harry).

Unfortunately, I never tested DVD with the other 2.6.0 kernel releases.

   I had it occasionally in the 2.5.X series, as well as with 2.6.0-test2.
To me it seems like some apparently unrelated config setting causes this.
I'd go over the config again, change a few settings that seem to make
sense - but nothing obvious - then recompile and get a healthy kernel.

   I'm using Grub and ext3, for the record.

Re: 2.6.0-test3 cannot mount root fs

[Norbert Preining]

Thanks to all of you for the several suggestions, but none was
successfull till now:

I tried as boot cmd line:
	s root=03:41 acpi=off
and still it didn't work. Same problem.

And I am not using devfs.

My lilo looks like this:
boot = /dev/hda2
install = /boot/boot-bmp.b
bitmap = /boot/debian-bootscreen-woody.bmp
bmp-colors=1,,0,2,,0
bmp-table=120p,173p,1,15,17
bmp-timer=254p,432p,1,0,0
read-only
prompt
timeout=100
password=""
  mandatory
vga=0x317
...
image=/boot/vmlinuz-2.6.0-test3
        label=2.6.0-test3
        append="amd_disconnect=yes"
        read-only
        restricted

Where amd_disconnect a patch is which sets a bit in the pci register to
allow the athlon to disconnect during idle, which greatly decreases my
cpu/mobo temperature. But this is not done till the place were the root
fs should have been loaded.

It is decimal.  You want 03:65.


Could you test this patch?  It should put things back to the way
they were before this mini-fisaco. root=0341 should work as well.

Still no success. With acpi=off and without.

Also no success.

Maybe I am stupid, but 
	make mrproper
	make distclean
	make config deb bzImage modules modules_install
should be enough to make a clean kernel? And, AFAIK, I compiled in ext3
and all other necessary stuff. Soon I give up.

make config
make

should be sufficient (dep, bzImage, modules is not required)

maybe you could provide your .config?

Re: 2.6.0-test3 cannot mount root fs

[Herbert Pötzl]

Hi Norbert!

your config seems reasonable to me ...

> I tells me all the usual stuff concerning that it finds 
> the controllers (VIA and HPT) and disks/cdroms, but than

AFAIK, there is no such message in 2.6.0-test3 ...

if, on the other hand, the message looks like ...

-----------
VFS: Cannot open root device "hdb1" or unknown-block(0,0)
Please append a correct "root=" boot option
-----------

then this means that "hdb1" was the device given at
the kenel command line (as root=/dev/hdb1) and the
'unknown-block(0,0)' is the major/minor the kernel 
recognized ...

you should pay special attention to the disc/partition
discovery done by the IDE subsystem ...

maybe you could attach a serial console (line)
and capture the boot process, and report it ...

unfortunately this line is missing in your copy ...

Are you using an initrd image and if so, are you using the new
initrd-tools?  I was having this problem before upgrading
initrd-tools. 2.6 does not support compressed ROM initrd images, so
even though it sees your partitions it can't load the _initial_ root.

No, but to be on the sure side I rebuild a kernel with
	CONFIG_INITRD is not set
and got the same effect.

I think I give up. Hundreds of Alt-PrintScr-b are disturbing ;-)

Ok, here is the exact output with different root= options:

root=/dev/hdb1
	Cannot open root device "<NULL>" or hdb1
	Please append a correct "root=" boot option

root=0341

now this makes some sense ...

here obviously root wasn't set to a string, but
device hdb1 is passed as in kernel setting?

this seems correct, but maybe some bug kicks in ...

the other options are obviously passed as root=
but can not be interpreted/resolved to a device

my assumption would be that you use the lilo root option
and do not pass the root= as kenel boot option ...

I would suggest to give append="root=/dev/hdb1" a try,
and/or update lilo or change to grub ...

I tried *all* the variants with passing
	root=....
on the lilo line, so it is passed to the kernel and not via rdev or
something else.

The hard disk is an IC35L...:
(running 2.4.22-rc2):

[~] cat /proc/ide/hdb/model 
IC35L040AVER07-0

So it *IS* recognized. But why not mounted.

I'm getting the same sorts of error messages with grub.  Here's the
grub.conf file...originally generated by a Redhat 9 install.

2.4.20 works with root=0303.  But I've tried all the variants after root=
(03:03, 0303, hda3, /dev/hda3) and nothing works

I have a hard time believing that 2.6.0-test kernels have this bug.  There 
must be something else going on here.  This is my grub.conf file:

If you're running RH9, try the non-kernel RPMs found at
http://people.redhat.com/arjanv/2.5/RPMS.kernel/

I haven't had any trouble getting 2.6.0-test started with these.

The solution is:
	Get a COMPLETE linux-2.6.0-test3.tar.bz2
and 
	DO NOT USE patch

I patched up the kernel from 2.5.20 or something and there seemed to be
an error somewhere on the way up. Getting a *clean* kernel tar file,
compile with the same .config, running.

This is the use of patches!

well, I always do make distclean after patch ... I cannot afford

I *ALWAYS* do 
	make distclean
and
	make mrproper
and all other incantations of cleaning, too! This was NOT the problem,
but a wrongly diff file obviously messed up the kernel.

Nope...  For the reported problem I had with grub and root=/dev/hda3, it was
with a fresh tar file.

As someone said, this "can't happen".  And as someone else said, "It comes
and goes with random changes in .config file"

so is there still somebody who is not able to boot,
despite of 16 different versions of root=wossname?

if so, I'm willing to make a small patch, which does
_a_lot_of_ status output and checks around this
code ... so it might be possible to track down any
issues/bugs ...

pleas let me know,

2.6.0-test3 _still_ cannot mount root fs

[jeff millar]

Redhat's 2.4.20 will boot with root=/dev/hda3 pointing to an ext3
filesystem, without an initrd, with the following message

   ext2fs warning (device IDE0(3,3) )  ext2_read_super: mounting ext3
filesystem as ext2
   VFS: mounted root (ext2 filesystem) readonly

So I assumed that 2.6.0-test3 will also work with ext3 compiled as a module.
I tried the various suggestions root=/dev/hda3, root=0303, root=03:03
without any luck.

I then tested a suggestion that ext3 should get compiled in but get the same
results

Herbert's debug patch produced the same messages with ext3 compiled in.

Any suggestions for what to try next?

appended a short patch, which goes ontop of my other
debug patch ... this time, please concentrate on the
%% lines and the lines immediately above and below ...

I'm pretty sure the problem is related to the file 
usr/initramfs_data.S. This file is automatically created by the
usr/Makefile, but not deleted by mrproper or distclean (in -test1). 

See l-k thread "remove initramfs temp files" of Aug 8.

The patch to -test2 contained the file usr/initramfs_data.S, and the
patch process fails since it's trying to create it. I ended up
accidently with garbage in usr/initramfs_data.S, to the effect that
the symbol .init.ramfs was empty (could be told from System.map),
which in turn had the effect that in init/initramfs.c the function
unpack_to_rootfs() was called with a length of 0 (&__initramfs_end ==
&__initramfs_start), which in turn prevented this very initial root
file system which is needed to mount root.

A warning message in unpack_to_rootfs() if it is called with a length
of 0 would have been very helpful.

Having make distclean remove initramfs_data.S would be very good
practice as well.
