New log of kernel 2.6.20-1.2922 panic none

Description Zhang Yanmin 2007-01-22 08:20:29 UTC 
Description of problem:
I used rpm to install the latest kernel and it hanged when rebooting.
The output:
Kernel panic - not syncing: No init found. Try passing init=option to kernel

Version-Release number of selected component (if applicable):
kernel-2.6.19-1.2912.fc7.ia64.rpm

How reproducible:
Everytime

Steps to Reproduce:
1. Use yum to upadte mkinitrd on my FC6 ia64 machine.
2. Run #rpm -ivh kernel-2.6.19-1.2912.fc7.ia64.rpm
3. Reboot
  
Actual results:
Hanged.

Expected results:
Kernel boots well.

Additional info:
1) I checked initrd.img and found there is an init script.
Comment 1 Prarit Bhargava 2007-01-22 16:35:12 UTC 
Yanmin, could you attach the console log so I can see where the hang was?

Or does the system not boot the kernel at all?

P.
Comment 2 Zhang Yanmin 2007-01-23 03:37:06 UTC 
Prarit,

The system could boot kenel, but kernel couldn't find /init. So it looks like an
initrd issue. I did an initial check of initrd.img and didn't find anything
abnormal.


I tried to capture log by serial port, but it didn't work. Below is something I
copied from the console.

I tried kernel-2.6.19-1.2914.fc7.ia64.rpm. Kernel hanged on one of my
machine(Montecito+Fusion SCSI disk). Pls. see the attached log.

New log of kernel 2.6.20-1.2922 panic

I rebuilt kernel 2.6.20-1.2922 with patch of ata/ata_piix to convert GSI to
irq.

Then, rebuilt a new DVD image. kernel panic on my tige-4 Montecito machine.

With the same vmlinuz/initrd, my Madison machine and Hitachi machine don't
panic.

My Hitachi machine is also Montecito. processor info:
arch	   : IA-64
family	   : 32
model	   : 0
model name : Intel(r) Itanium(r) 2 Processor 1.6GHz with 24M L3 Cache for
533MHz Platforms
revision   : 5
archrev    : 0


Tiger-4 Montecito machine processor info:
arch	   : IA-64
family	   : 32
model	   : 0
revision   : 4
archrev    : 0
Comment 6 Zhang Yanmin 2007-02-12 09:10:28 UTC 
Another difference between my Hitachi and tiger-4 is I disable multi-thread on
hitachi and enable it on tiger-4, because hitachi booting becomes very slow if I
turn on multi-thread.
Comment 7 Dave Jones 2007-05-15 20:25:41 UTC 
is this reproducable with f7test4 ?
There were a large number of mkinitrd fixes just before its release which may
have helped.

Dave,

Sorry. I'm very busy in other tasks and have no time to check it.

This has been verified to be resolved on the F8 kernel.
