Description of problem:
Capture kernel failed to capture a vmcore for IBM eServer x3455. It reseted to
BIOS after the following messages,

cpu cores) (version 2.20.00)

I have tried "noacpi" to kdump kernel command-line, and RHEL5U1 version of
kexec-tools without luck. Note that the problem is only triggered by certain
crash scenarios. For example, LKDTM (Linux Kernel Dump Test Module)'s bug in
do_irq(). Simple "echo c >/proc/sysrq-trigger" works perfect fine without
problem. I have not tried this with i386 or RHEL5U1 kernel yet.

Version-Release number of selected component (if applicable):

How reproducible:
Always on ibm-pizzaro.rhts.boston.redhat.com

Steps to Reproduce:
1. configured kdump and booted the kernel with crashkernel=128M@16M.
2. wget
http://porkchop.devel.redhat.com/qa/rhts/lookaside/ltp-kdump-20080228.tar.gz; cd
kdump/lib/lkdtm; export USE_SYMBOL_NAME=1; make
3. insmod lkdtm.ko cpoint_name=INT_HARDWARE_ENTRY cpoint_type=BUG cpoint_count=05

Neil suggested the following patch might be helpful here.

Comment 4 Qian Cai 2008-04-03 15:15:26 UTC
Same thing happened for i386 as well.

Comment 5 Qian Cai 2008-07-16 10:09:34 UTC
I have tried the following options to Kdump Kernel options, and it does not help.

"hda=noprobe hdb=noprobe hdc=noprobe hdd=noprobe"
"ide0=noprobe ide1=noprobe ide2=noprobe ide3=noprobe"

So, I suppose I'll wait this machine gets BIOS updated first.

Comment 6 Qian Cai 2008-10-22 10:34:02 UTC
I'll close this out, as using jprobe() to trigger artificial crashes probably not a good way to test Kdump. I'll create a new Kernel module to test those scenarios and open new BZs for any issue found.
