Subject: Re: [Bug #32982] Kernel locks up a few minutes after boot

Is this machine running a RAID5 setup or something like that?

There is a known interaction with the new block layer plugging code
and MD. The "hung task" report in that bugzilla looks very much like
that issue. And you do have "root=/dev/md0", so clearly there's some
md thing going on.

And bisecting might not work all that well for it, because I suspect
it ends up being very much a matter of IO patterns how it triggers.

Neil supposedly has a patch for it, but I haven't seen it yet. Neil, Jens?
