Zou,
I got this information. Actually the situation is even worse than I imagined.
According to Ben who is working on this those are:
--------------------
"To sum up what happens, I do this using the default kernel command line
(and also one with "debug console=uart,io,0x3f8,115200n8 console=tty0"
added to it):
# kexec -l /boot/efi/efi/redhat/vmlinuz-2.6.18-8.el5
--append=`cat /proc/cmdline`
--initrd=/boot/efi/efi/redhat/initrd-2.6.18-8.el5.img
# kexec -e
The old kernel shuts down and boots the new one successfully, but, the
new kernel causes a fault during its boot. I can't positively identify
the exact spot it crashes because the serial output stops. Going by the
screen, it is either during or immediately after the ACPI system tries
to detect all of the CPUs. On a couple occasions I've seen it spit out
something along the lines of "EFI Time driver" before it blanks the
screen out, but it does it very quickly and the Raritan doesn't update
fast enough, even if I'm sitting at the cold floor display.
The system is configured with a single CPU, as multiple CPUs cause a
different error, something along the lines of "huh? CPU #0x200 is
already present" - but this also happened on the system without the
capacitor fix. Turning on and off hyperthreading doesn't seem to matter
either.
Here is entire log and a screen capture of the last things that
show up on the video console. The /proc/iomem contents are at line 460
in the log, and the kexec I used is at the very end. The second kernel
doesn't get far enough to enter any commands, so I'm
afraid I can't get you the /proc/iomem for that."
--------------
Please advise where he can look to analyse this.
Thanks!
