Of course I am not an expert here, but I want to rule out some trivial 
userspace things first.

Some time ago Greg KH said that even when the modprobe command returns, there 
is no guarantee that the module finished hardware detection. By rebuilding 
ata_piix as a non-module, you changed the timeline.

Could you please, for debugging, recompile ata_piix as a module again, but add 
a "sleep 5" before the mkrootdev command? If that works, a bug (race) is 
officially in userspace.

Sorry if all of the above is in fact just meaningless noise.

sleep 5 before mkrootdev fixes it. Attached is working dmesg with
module and sleep.

ata_piix had been working as a module for over a year so something
recent disturbed the timing.

current linus bk, error mounting root

[Jon Smirl]

Something in the last 24hrs in linus bk broke my ability to mount root:

Creating root device
Mounting root filesystem
mount: error 6 mounting ext3
mount: error 2 mounting none
Switching to new root
Switchroot: mount failed 22
umount /initrd/dev failed: 2

If I back off a day everything works again. 

Root is on Intel ICH5 SATA drive.

dmesg output?

Can you verify that -bk4 works, and -bk5 breaks?

bk4 works. I don't have a serial port hooked up so there is no way to
get dmesg, but I don't see anything obvious on the screen scrolling
by.

I'll check bk5 next.

It would be much more convenient if the bkN releases were tagged in Linus bk.

No need for tags, that's what the *.key file is for.

Well, there are no changes in libata from bk4 to present.  The only 
thing I see in the -bk4-bk5 increment diff that's immediately noticeable 
is the barrier stuff.

bk4 works
bk5 is broken

Where are these *.key files? Maybe I can do some more divide and
conquer in bitkeeper.

probably not worth the bother, looks like barrier problems. get the
serial console running instead and send the full output, I'll take a

Hmm ok, nothing of interest there. What does the mount error 6 and 2
from  your original mail mean? I need some more info on what fails
specifically. What mount options are used? What partition is mounted (is
it md or hdaX)?

I'm not sure -bk5 had the follow up fix patch for the barrier rework,
you should probably just retry with -bk6 first.

I am still broken with using the Linus bk tree as of when I wrote this

if 6 is the errno, it looks like it is trying to open a device that does
not exist (ENXIO). Can you up the verbosity of those commands, I'd like
to see what it is doing exactly.

Jeff, how can I up the verbosity? This is on Fedora Core 3 but before
user space is up. Is there some way to tell the boot ramdisk to
display more info?

Perhaps you can mount the initrd and change the script to echo the
commands before executing them? Then boot with the modified initrd.

Here's what it is doing... looks like the first mount is failing

echo Creating root device
mkrootdev /dev/root
umount /sys
echo Mounting root filesystem
mount -o defaults --ro -t ext3 /dev/root /sysroot
mount -t tmpfs --bind /dev /sysroot/dev
echo Switching to new root
switchroot /sysroot
umount /initrd/dev

what are the major/minor numbers of /dev/root?

If I boot on a working system it is 8,5

mkrootdev is a nash command

       mkrootdev path
              Makes path a block inode for the device which should be mounted
              as  root.  To  determine  this device nash uses the device sug-
              gested by the root= kernel command line argument (if root=LABEL
              is  used devices are probed to find one with that label). If no
              root=  argument  is  available,  /proc/sys/kernel/real-root-dev
              provides the device number.


I already tried switching from the label syntax to /dev/sda5 without effect.

I see no /dev/sda detected in your system from the dmesg. Ahh this is
where it panics on loading ata_piix I suppose, can't you capture that
panic with the serial console as well?

I see:
Loading libata.ko module
Loading ata_piix.ko module
ACPI: PCI interupt 0000:00:1f.2[A] -> GSI 18 (level, low) -> IRQ 169
ata1: SATA max UDMA/133 cmd 0xFE00 ctl 0xFE12 bmdma 0xFEA0 irq 169
ata2: SATA max UDMA/133 cmd 0xFE20 ctl 0xFE32 bmdma 0xFEA0 irq 169
then raid autorun, one of the raid partitions is on /dev/sda

No panic on ata_piix load.
The panix is on killing init, it is the standard panix from not having
a root device.

I just built it in instead as a module, I'll try that next and see if
says anything different.

Here's a big clue, if I build ata_piix in I can boot. If it is a
module I can't. The console output definitely shows that the module is
being loaded.

Can you post your config?

The attached config works. If you change CONFIG_SCSI_ATA_PIIX to a
module (make sure it is on initrd) it will fail. I have been running
with CONFIG_SCSI_ATA_PIIX as a module since 2.5.30 or so.

Re: current linus bk, error mounting root

[Jon Smirl]

Is this problem still being tracked?

I have figured out a work around of adding a 1 second pause in nash
after the ata_piix driver is loaded. Something has changed in the
driver initialization timing such that later stages of boot try to
access the driver before the driver has created the device without the
pause.

I am using Fedora Core 3 un modified except for the addition of the 1
second pause.

If the /dev showup timing is a problem, you were just lucky that it
worked before and I don't consider it a kernel issue.

Yes, and name them -preN instead. ;)

I had a slightly different problem mounting root with an earlier -mm, which
was fixed by setting CONFIG_BASE_FULL=y.  I saw that option enter the
Linus tree recently, so that might be something you could try.

I don't agree that this is a userspace issue.  It's just not sane for a
driver to be in an unusable state for an arbitrary length of time after
modprobe returns.

You can't do that on any udev based system reliably.  That has _never_
been true.  You might just have been getting lucky in the past.

That's still racy.  Rely on the /etc/dev.d/ notifier to be able to tell
you when you can mount your device, that is what it is there for.

This is a udev issue, not a kernel issue, there's nothing we can do in
the kernel about it (well, except for the obvious thing of giving udev
lots of hints and making it easier for it to work properly and faster,
which we have been doing over the past months.)

It is a userspace issue.  If you have a static /dev there are no
problems, right?  If you use udev, you need to wait for the device node
to show up, it will not be there right after modprobe returns.

OK, that's different.

(grumble, mutter)

It would be very convenient, tidy and sane if we _could_ arrange for
modprobe to block until the device node appears though.  I think devfs can
do that ;)

Heh, the sound people went through the same grumblings a few months ago
:)

devfs _can_ do that, as it waits on the register block device to create
the node.  All udev can do is act apon the call to hotplug as fast as it
can (in the correct order).  The kernel issues the call and then
returns, causing modprobe to return.

The distros that use udev have already all worked out these issues with
their init scripts and such, so it shouldn't be an issue anymore.

Jon, what distro are you using?

The mkinitrd script is broken for up2date Fedore Core 3. udev is not
building the sata device in time. The script does: '/sbin/udevstart',
'raidautorun /dev/md0'. I just checked and the sata volumes are
missing out of my array.

This script used to work and changes after 2.6.11 have thrown off the
timing so that it doesn't work anymore.

echo "Loading libata.ko module"
insmod /lib/libata.ko

Re: current linus bk, error mounting root

Here is fedora's initrd nash script from my system. I modified it with
the sleep lines.

It already is creating the /dev node with 'mkrootdev /dev/root'
I don't think udev is even running yet. Something else is causing this.

echo "Loading libata.ko module"
insmod /lib/libata.ko
echo "Loading ata_piix.ko module"
insmod /lib/ata_piix.ko
echo "Loading raid1.ko module"
insmod /lib/raid1.ko
/sbin/udevstart
raidautorun /dev/md0
>>>echo Sleep 1
>>>sleep 1
echo Creating root device
mkrootdev /dev/root
umount /sys
echo Mounting root filesystem
mount -o defaults --ro -v -t ext3 /dev/root /sysroot
mount -t tmpfs --bind /dev /sysroot/dev
echo Switching to new root

mkinitrd in Fedora needs to be modified to wait for the device. 
Maybe something like a nash command like wait /dev/sda1.

What about if I'm booting from a USB drive?  In that case, because of 
the
asynchrony of USB probing, it may take 1 or 2 seconds for my attached 
hub
to power on, wake up, boot its embedded microprocessor, etc before it 
will
respond to signals.  In such a case, as far as the root hub can tell,
there are _no_ external devices for a couple seconds, and that's 
ignoring
that my external USB bootdrive may _also_ need time to "boot" before it
will be accessible, and that's only once its parent hub has become
available.

I think that the kernel needs some kind of wait-for-device API that is
accessible from kernel-space for the simple boot sequence, perhaps just
waiting for a specific kobject to be detected and complete 
initialization.

For an initrd/initramfs in userspace, dnotify on sysfs (For the static
/dev case), or dnotify on /dev (For the udev case) should allow it to
detect when the device is available.

That's a different issue, as you stated.  There are other patches
floating around that address this.
