A few updates. Running on a wired connection has resolved the corruption and hanging, at least so far; including situations that were triggering it before, such as pulling a torrent onto the eSATA drive.
However, it has panicked twice now upon shutdown after the "will now halt" message. (This is out of 20+ shutdowns or so, I estimate). I took a picture the second time & it's attached; the 'ieee80211_stop' line seems to point at wireless problems still. I've installed linux-crashdump, but I haven't been able to persuade it to do its job yet. Google hasn't been very useful, and it's deadline season with my work so I can only pick at the issue. (Perhaps I need to edit the kernel parms for grub?) ** Attachment added: "DSCF0630.JPG" http://launchpadlibrarian.net/27787764/DSCF0630.JPG -- Disk corruption and complete freezes. :( https://bugs.launchpad.net/bugs/381327 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
