ahcicam hang ups?

[Peter Avalos <peter@xxxxxxxxxxxx>]

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?
