Hello,
I've been playing around with my kernel (sounds almost rude) on our z890
LPAR (via sources from kernel.org) and received the following error after
upgrading. Everything stills boots up fine. I am not sure what this error
is indicating or what is its cause.
Upgraded to kernel level 2.6.18 with prepatch 2.6.19-rc1. I was previously
at 2.6.5 and did not encounter these lockups.
Anyone else out there on s390 at this kernel level with any issues or
anyone know where I might start looking for cause!
Take it easy on me ... I'm new!!
Greg
