Re: [LKP] [lkp] [test] 265bbb5704: BUG: unable to handle kernel paging request at e8e04dec
by Luis R. Rodriguez
I've been making some changes to fix this before posting patches, and
pushed a few branches out to kernel.org a few days ago now but haven't even
heard of a build status which typically has taken about ~3 hours or so.
Now I haven't heard from 0-day for a few days about build / tun time status
of a few branches I've pushed out both on my linux.git and linux-next.git
and starting to wonder if there may be an issue or real long term
maintenance thing going on ? The sysdata branches also had a timout occur
on one build so wondering if perhaps there are rules that put your trees or
branches in a dark corner to avoid delays in 0-day ?
How do I check to make sure I'm OK ?
