can you capture any information from the panic ? (Even a digital camera photo of
the screen is better than nothing)

(Also, make sure you remove 'quiet' from the boot command line).
Comment 3 Dave Jones 2005-12-14 09:32:19 EST
also, please attach your /etc/modprobe.conf

I just upgraded 2 very similar servers to 2.6.14-1.1653_FC4smp.  One came up 
fine, the other panics in boot-up with errors like:

md: ... autorun DONE.
Creating root device
Mounting root filesystem
EXT3-fs: unable to read superblock
mount: error 22 mounting ext3
Switching to new root
ERROR opening /dev/console!!!!: 2
error dup2'img fd of 0 to 0
error dup2'img fd of 0 to 1
error dup2'img fd of 0 to 2
unmounting old /proc
unmounting old /sys
switchroot: mount failed: 22
Kernel Panic- not syncing: Attempting to kill init!

Both servers are smp [dual PIII-800mhz], same tyan mobo, with 2 SCSI disks.  
Both are running software RAID (with similar partitions: /dev/md0 is /boot 
and /dev/md1 is /).  There are several slight variations in their installs.

Both servers have the same /etc/modprobe.conf  :
# cat /etc/modprobe.conf 
alias eth0 tulip
alias scsi_hostadapter aic7xxx

Booting the previous kernel (2.6.14-1.1644_FC4smp) on the panicking server 
works, so I've dropped back to using that.  I've looked around, but I don't see 
what changed in 1653 to trigger this now.

Comment 8 Dave Jones 2005-12-23 14:37:48 EST
Tanikumahousei, what type of disk hardware do you have ? SATA ? SCSI ? IDE ?

Bill, I'm totally puzzled.  We get a bunch of reports like this every time I
push an update, where nothing changed in a particular driver, yet it blows up
for some folks, but not others.  Nearly every time, it's an mkinitrd failure of
some sort.
Can you attach the /boot/initrd-2.6.14-1.1653_FC4smp, and I'll have a poke at it
to see if I spot anything obvious.  (Something just occureed to me- if its an
old server, it may not have a fully acpi compliant bios, and this update
disabled the y2k-cutoff check, so we're using acpi on older systems now too. 
Try booting with acpi=off)
Comment 9 Bill Marrs 2005-12-24 07:41:33 EST
Dave, thanks for the clue!  Sure enough, the nearly identical server that 
didn't have a problem had acpi disabled in its bios.  But, the non-booting 
server had acpi enabled.  So, I disabled acpi for the non-booting server and it 
came up just fine.  So, your guess was right on the money and I'm happy as a 
clam now.

Checking old /var/log/messages on the non-booter, I see this from last week:

Dec 18 10:55:05 essrog kernel: ACPI: BIOS age (2000) fails cutoff (2001), 
acpi=force is required to enable ACPI
Dec 18 09:57:12 essrog kernel: shpchp: acpi_shpchprm:get_device PCI ROOT HID 

After disabling ACPI in the BIOS, that "BIOS age" line no longer shows up.

My motherboard is a "Tyan S1834 Tiger 133", if that's any help.  It's certainly 
kind of old these days (circa 2000, I think).  I don't care about ACPI support, 
though.  This server never sleeps, it's SMP as well, so APM doesn't even work 
(I think).  

I suppose what's happening is a bug, so if you want to track or follow-up with 
that, I'd be happy to try out fixes for it.  This server does run a couple live 
websites, but I can reboot it in the morning without much trouble.

Thanks again
Comment 10 Dave Jones 2005-12-24 15:34:13 EST
on the server that has problems, try pci=noacpi instead of acpi=off
output of 'dmidecode' (as root) would allow me to add this to a blacklist too,
so that future updates 'just work'.

dmidecode output
Comment 12 Bill Marrs 2005-12-25 13:34:51 EST
Yes, booting with acpi enabled in the bios and pci=noacpi also works.

So, there are 3 way this machine will boot now:

1) disabling acpi in the bios
2) acpi=off
3) pci=noacpi 

I've attached the dmidecode output as well.  

Thanks again for your help, Dave.

I am Tanikumahousei.
I have SATA and IDE.
Both SATA and IDE are bad !
