Title:
powerpc/powernv: Flush console before platform error reboot
Status in linux package in Ubuntu:
New
Bug description:
Unrecovered MCE and HMI errors are sent through a special restart OPAL
call to log the platform error. The downside is that they don't go
through normal Linux crash paths, so they don't give much information
to the Linux console.
We need to have the commit b746e3e01e70d23ef53dcde1203ab78a1b7ac514 in
kernel 4.10.
I did the backport and that will be attached to this bug.
I also tested kernel -41 with this patch in several scenarios (KVM
guest, Hypervisor) and I see no regression
