Hi Bastian,
I imagine -39 works for you since the changes from -38 to -39 were
rather small, and therefore it is actually -40 which contains the
problem.
My best guess is that this is caused by the patches I added for #638172
in SVN r18375. Could you try with them reverted to confirm? It's the
entirety of the penultimate block of patches in
debian/patches/series/40-extra.
I've crawled over the diff between the current Debian tree and the
xen.git#xen/next-2.6.32 tree and the event handling stuff is basically
identical so I'm at a loss to explain why these would have broken things
(and this kernel works for me). :-/
Please could you post the boot dmesg of both a native and xen boot of
the same -40 kernel binary? Also /proc/interrupts might be interesting
to compare. If you have time you could also provide the same for -38
booted on xen, just for comparisons sake.
Thanks,
Ian.
