Description CAI Qian 2008-07-28 03:53:47 EDT
Description of problem:
Kdump is not working on an IA64 box (hp-bl860c-01.rhts.bos.redhat.com). Capture
Kernel failed right after loading cciss module. It is not a regression though,
as it has been masked by another CCISS driver bug (hung in MSI mode), which
seems has just been fixed in RHEL5.2.

Comment 1 Doug Chapman 2008-08-28 13:26:33 EDT
I will take a look at this.  I have tested kdump on several other HP ia64 systems w/cciss and have not seen any issues so if it is broken here it might be due to the specific model of cciss card or possibly just out of date cciss firmware which I can update.

We also have an updated version of the cciss driver posted but not yet pulled into RHEL5.3.  I will try that also.
Comment 2 Doug Chapman 2008-08-28 17:59:20 EDT
OK, wasn't as simple as I thought.  I tried all the above with no luck.  reassigning to myself and I will investigate.
Comment 3 Luming Yu 2008-08-29 02:32:56 EDT
The crash message seems to indicate "kexec -e" doesn't work...
Could you verify if "kexec -e" works on this box with cciss module loaded?

Comment 4 Doug Chapman 2008-08-29 12:52:09 EDT
This is broken hardware.  I tested an identical system back at HP with identical firmware revs and it works properly.  Also I have tested kdump on every other HP ia64 system I can get my hands on and this is the only place it fails.  I will work on getting the hardware fixed next week.
