initial console

[Xavier Grave]

Hi,

I have the following message at boot :

Freeing unused kernel memory: 220k init 12k pmac 4k chrp 4k openfirmware
Warning: unable to open an initial console.
Kernel panic: No init found.  Try passing init= option to kernel.
Rebooting in 180 seconds..

if I give this argument init=/sbin/init it's the same.

Also hen I try to enable virtual terminual I have the following very early:

TCP: Hash tables configured (established 4096 bind 4096)
Starting kswapd v1.8
pc_keyb: controller jammed (0xFF).
pc_keyb: controller jammed (0xFF).
and so on...

Thanks in advance for anyhelp.

CONFIG_SERIAL_CONSOLE is missing ?
console=ttyS0 in the kernel boot args ?

Expected with an MVME2300.

P.S:  I still don't understand why my bootloader would not properly
reconfigure the PCI resources to give you access to the SCSI board.
Do you have somewhere a printout of the bootlog, it should list all the
PCI resources before and after reorganization.

What does /dev/console look like?

Did you enable any device that can provide a console functionality, like e.g.
CONFIG_VT, CONFIG_SERIAL_CONSOLE?

The error message disappeared after a few hundred of message.

Sorry, I've lost the output of the kernel I have compiled with your patch.
Can I use your patch with the latest linuxppc_2_5 from fsmlab ?
If so I'll try it one more time. But the actual kernel (from
fsmlab) recognize and configure my SCSI board.

No, all my patches are relative to the official kernel tree. I have
2.4.0-test9 running on an MVME2600 right now (built in NCR53C825).
It might be a sym53c8xx driver problem too, I have only used ncr53c8xx.

I know it sounds dumb, but have you ensured that you've got the root partition
set correctly?  I've seen these errors before when I had a root partition
specified that didn't contain /dev or /sbin/init.

Perhaps add root=/dev/<whatever it is for you> as another arguemnt.

/dev/sda5 on / type ext2 (rw,errors=remount-ro,errors=remount-ro)
proc on /proc type proc (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/sda2 on /boot type ext2 (rw)
/dev/sda6 on /home type ext2 (rw)
/dev/sda7 on /export/data1 type ext2 (rw)
/dev/sda8 on /export/data2 type ext2 (rw)

And I give the following argument root=/dev/sda5
with the 2.4.0 kernel it fails but with a 2.2.17 kernel it works.

Re: initial console

[Alois Fertl]

The problem you are seeing here is probably prep_init in prep_setup.c
not copying the arguments passed by the boot loader into the kernels command
line. Your root=/dev/sda5 is probably ignored.
Look at your early log messages during boot. There should be a line
"Boot arguments: ..." telling you those things seen by the kernel.

In case the arguments aren't as you typed them, try putting the following
lines at the beginning of prep_init:

+       if (r6) {
+               *(char *)(r7 + KERNELBASE) = 0;
+               strcpy(cmd_line, (char *)(r6 + KERNELBASE));
+       }

What hardware is this running on? If it is Motorola VME this failure is only
the starting point and other trouble will follow. There are additional fixes
but I can't verify them against a working source at the moment. test9 and test10
from fmlabs currently both panic during init as soon as the process starts using
the hard drive (this is on a PowerStack).

Indeed, The kernel argument I give is :
root=/dev/sda5
and during the boot when I look more closely :
PReP architecture
Boot arguments: /dev/sda1

Ok, this is fine my kernel boots ! Thank you very much.

I have a MVME2303 from motorola diskless + a PMC with a 53c895 pci board
for my disk. With the 2.2.17 kernel all works well.
And now with the latest fsmlabs + your hack all function !

Major 5 minor 1 is correct.

Sorry, I had this change locally but hadn't pushed it yet. :)  The other
option on PReP is to build with /dev/nvram support and then (on a
PPCBUG system) use 'gevedit bootargs' to set a kernel argument command
line like "root=/dev/sda5".  That's often more convenient then hard
coding in your parameters like with the PReP cmd_line config option.
