Title:
Kernel 4.15 boot error on XenServer
Status in linux package in Ubuntu:
Confirmed
Bug description:
I recently upgraded an ubuntu VM from 16.04.1 to 18.04.1 running on
XenServer 7.1. The upgrade itself was fine, but several kernel updates
after the upgrade have caused the VM to fail to boot. All kernels that
fail to boot seem to be from 4.15. Current, the latest kernel I've
tried is 4.15.0-38, though, day-to-day I'm running a 4.4 kernel since
the VM is necessary to my environment.
The error message on boot is:
unchecked MSR access error: RDMSR from 0xc90 at rIP: 0xffffffff9806c04a
(native_read_msr+0xa/0x30)
The trace is attached as a screenshot. I haven't been able to get a
log containing the output.
