Description bastiaan 2005-08-07 15:23:42 EDT
Description of problem:
Booting the xen0 kernel fails on a Compal CL65 laptop. 

Version-Release number of selected component (if applicable):
2.6.12-1.1398_FC4xen0

How reproducible:
always

Steps to Reproduce:
1. boot kernel 2.6.12-1.1398_FC4xen0
  
Actual results:
at boot time xen complains about routing conflicts for IRQ5 for PCI device
02:03.0 and subsequently the kernel hangs at the point in rc.sysinit where it
loads kernel modules for PCI devices.

Expected results:
the xen0 kernel should boot properly.

Additional info:
PCI device 02:03.0 is the CardBus bridge device. A simple workaround to the boot
problem is to disable loading of the yenta_socket kernel module in rc.sysinit.

Comment 2 Fedora Update System 2005-08-26 17:36:59 EDT
From User-Agent: XML-RPC

A new Xen version has been pushed to Fedora Core 4 updates.  This version of Xen (combined with the latest kernel update) should fix this issue.

Please reopen this bug if the problems continue with the latest Xen and kernel updates.

From User-Agent: XML-RPC

A new Xen version has been pushed to Fedora Core 4 updates.  This version of Xen (together with kernel 2.6.12-1.1435 or newer) should fix this issue.

Please reopen this bug if the problems continue with the latest Xen and kernel updates.

I've tried kernel-xen0-2.6.13-1.1526_FC5, but it fails even earlier with the
message:
Domain 0 allocation is too small for kernel image.

explicitly setting dom0_mem in the boot config doesn't help. 

I'll try 2.6.12-1.1435 next.
Comment 5 Rik van Riel 2006-02-08 20:50:49 EST
This should work on current Xen packages from Fedora Core 5 rawhide.
