Resend: Sorry copy and pasted a wrong mailadress for the xen-devel list. Hi Boris / Juergen, This morning i got this dom0 kernel crash (it occurred sporadically before (during 4.11), but i didn't have serial console enabled at that time so i had no stacktrace, only sporadic reboots). It's running on an AMD phenom X6: Kernel 4.11.0-rc7 with as latest commit: 94836ecf1e7378b64d37624fbb81fe48fbd4c772. Xen-unstable with as latest commit: 94836ecf1e7378b64d37624fbb81fe48fbd4c772. If you need more info please ask, testing will be difficult as i don't have a clear testcase and it can also run for days without trouble. -- Sander [ 39.696900] ------------[ cut here ]------------ [ 39.704630] kernel BUG at drivers/xen/events/events_base.c:1221!
