Hello.
I have tried to compile linux 2.6.38.5 and got kernel panic on:
Kernel panic - not syncing: IO-APIC + timer doesn't work! Boot with
apic=debug and send a report.
So i googled and found this thread:
http://purak.org/blog/2011/03/19/gcc-4-5-2-and-linux-kernel-2-6-38-are-problematic/
And that was my case. So gcc 4.5.2 + linux 2.6.38>= ARE problematic.
Recompling with RELOCABLE=off and PHYSICAL_START=0x10000 helped.
Kernel 2.6.38.5 boots and copy of CD to ISO is working.
Regards, Peter

Ok. Thanks.
I already reposted to linux-fsdevel (my mistake).
And I will also repost to linux-kernel without attachments. (As i am
newbie to linux-kernel mail list)

Hello.
I have done this redirect and I have got full stack trace.
See attached dmesg.txt. (here is the crash)
I have kernel 2.6.38.3 and also .config and boot.dmesg is attached.
Any clues? Thanks.
As you can reproduce this bug easily, please try 2.6.38.5 before
reporting.
Secondly, not linux-fsdevek@xxxxxxxxxxxxxxx but
linux-fsdevel@xxxxxxxxxxxxxxx .
Your message was delivered to only me. :-)
Also, you should post to linux-kernel@xxxxxxxxxxxxxxx as your problem may
be
mm related rather than fs related.
Also, people generally don't open attached files.
You need to extract important lines like below.
