ahcicam hang ups?

[Matthew Dillon]

: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.
