Public bug reported: After upgrading to Ubuntu 11.10 and thus a newer kernel, when I 'Safety Remove' my Western Digital My Passport Essentials 500GB Hard drive I get a kernel panic (60% first time, if I reinsert and repeat i get about 95% second and always panicked by the third retry)
Whilst it occurs on safety remove, from what I can make out from kernel panic text (it won't make a crash dump, even with kdump, need help with getting this to work), it has something to do with a kernel thread failing to flush, and I see something about changing the vsync and hsync (which also appears in dmesg but succeeds). I can unmount the device and use the 'eject' command in terminal and take it out no worries, but If i 'safety remove' it panics. I am using a Kogan Agora Pro 12" Netbook (http://www.kogan.com.au/shop /agora-pro-12-ultra-portable-laptop-computer/) Here is some hopefully useful info: (as this relates to an external device I am following the bug report suggestions) cl-list-sessions: Session2: unix-user = '1000' realname = 'Kieran Grant' seat = 'Seat1' session-type = '' active = TRUE x11-display = ':0' x11-display-device = '/dev/tty7' display-device = '' remote-host-name = '' is-local = TRUE on-since = '2011-10-15T00:44:26.897478Z' login-session-id = '4294967295' id haldaemon uid=113(haldaemon) gid=124(haldaemon) groups=124(haldaemon) uname -a Linux kieran-netbook 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:56:25 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux I will attach some files recommended by the external device bug report page (dmesg.txt, lshal.txt, udev.log, and the devices associated (ls -l /dev/sdb*)). Also I'll add lsusb and lspci. It is reproducible and only occurs on Ubuntu 11.10 (I have a computer with Ubuntu 10.04 and it works find and I will have soon a bootable usb of 11.10 to try it on other hardware).
