Description

I've been having issues with parallel builds on my SMP laptop (and I
occansionally see this on ylem). Processes get stuck in the achicam
state, and my disk is pretty much useless after that. I can't get a
core dump, and in fact I can't even get the box to panic:

rama:~# sysctl debug.panic=1
load: 0.00 cmd: zsh 17678 [ahcicam] 0.00u 0.00s 0% 812k

I think Matt has seen this happen on ylem (the rtorrent that couldn't be
killed). I'm not sure what to do about this when the box is in this
state.

I think Sascha has also seen this.

Any suggestions?

I think the rtorrent issue is different than your ahcicam issue.
I've never seen the "ahcicam" issue before ever, it's a new issue.
I can start running parallel builds on my laptop(s) to try to
reproduce it.
