Date: Sun, 12 Aug 2007 11:30:22 -0700 From: "Peter Johnson" <johnson.peter@gmail.com> To: freebsd-stable@freebsd.org Subject: Crash in ata (owner=0x4) Message-ID: <1233f1b60708121130y791afbf0ma1fcc02dbaa69718@mail.gmail.com>
next in thread | raw e-mail | index | archive | help
Not doing anything special, just browsing in Firefox. I've had a
couple of different panics, but all have this weird owner=0x4. The
panic is in ata; maybe because I boot from da disks, my system
(usually) manages to stay up for a while before panicing... not in
this crash however. I have the core available for further debugging
if necessary.
Thanks,
Peter
