Description Frank Stanek 2008-02-14 22:32:28 UTC

The specified kernel panics early during boot with xen-3.2.0 (also xen-3.1.3). The only output I was able to get is this:

I have ruled out faulty SATA/PATA and USB drivers, not compiling them into the kernel does not help. However xen-sources-2.6.18-r8 boots fine with the exact same configuration and only stops much later due to missing SATA/PATA drivers.

Two other persons have reported a similar problem in the Gentoo forums:

I will attach my .config and the output of lspci for reference. Please advise if and how I can provide any more information.

Reproducible: Always

kernel config

This is the configuration I used for xen-sources-2.6.20-r6. It's an almost exact copy of my non-xen config.
