[Xen-devel] FC15: 32-bit PV guest crash on restore on x64_86 host
On restore 32bit PV guest crashes on x64_86 host, while x64_86 PV guest
works as expected.
Bisecting of upstream kernel shows following offending commit:
commit 448f2831934381e9d3c4d93e700ba7bbe14612dc

But since I do like fast builds, I''ve used fast PC with 2 NUMA nodes at least and it turns out that the bug is not reproducible on PC with only one cpu (HPZ800 1 socket config). So you can reproduce it if you try a PC with at least 2 cpus nodes.> _______________________________________________ > Xen-devel mailing list > Xen-devel@lists.xensource.com > http://lists.xensource.com/xen-devel_______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
