Description Tim Small 2005-11-24 11:52:38 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6

Description of problem:
The HP CISS (formerly Compaq CCISS) driver fails to see any controllers, when loaded within the xen hypervisor kernel (also tried multiple FC4 xen/kernel-xen0 combos).

HP Proliant DL380 G3
1x 2.8GHz Pentium 4 Xeon

Version-Release number of selected component (if applicable):
xen-3.0-0.20051109.fc5.3  kernel-xen-hypervisor-2.6.12-1.13_FC5

How reproducible:

Steps to Reproduce:
Install xen, kernel-xen-hypervisor-2.6.12-1.13_FC5, reboot, wail, gnash teeth.  I also tried building the ciss driver into the kernel, with the same lack of results.

Actual Results:  Boot fails - inaccessible root partition

Comment 1 Tim Small 2005-11-24 12:15:38 EST
Doh, my bad.  As part of the debugging that I was doing to 2.6.12-FC4-1456, I
tried disasbling IOAPIC mode on the xen command line.  This didn't fix the
problem, I then rebuilt the -devel FC5 kernel, and installed this, and the
kernel package carried the debug noapic setting over.  With this turned off, it
now works...

I will try and find out which kernel fixed it, and draft some changes for the
Fedora/Xen quickstart wiki.

Sorry for the bother...

Comment 2 Tim Small 2005-11-24 12:17:57 EST
To clarify, if I ommit the "noapic" xen boot time paramter, the
xen-3.0-0.20051109.fc5.3 + kernel-xen-hypervisor-2.6.12-1.13_FC5 combo now seems
to work...
