Hi, I have a Paravirtual DomU crashing on me at bootup on a newly setup Ubuntu 7.10 system. The system has 2.6.22-14-xen kernel and Xen 3.1. HVM guests are OK. I was running perfectly OK with this system at Ubuntu 7.10's beta stages, when there was 2.6.22-12-xen kernel, but when Gutsy is officially launched, I decided to wipe out my Dom0 and reinstall it. It came with kernel 2.6.22-14-xen and now crashing on me at bootup. In order to make sure that it's not Ubuntu specific, I installed Fedora 8 with 2.6.21 Dom0 kernel. I ran this DomU with 2.6.23 standard and 2.6.21 Dom0 kernels. No change, always same crash. So it seems that there's some issue here. Here's some log from the boot about the crash. It seems that something is related with atomic-ops, maybe it's possible to fix it within the DomU.
