** Description changed: - 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) + *** UPDATE *** - Confirmed not my netbook. + + 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/) + I have tested this on a Kogan Agora Pro 12" Running Ubuntu 11.10 x86_64 + and I Intel Core 2 Duo Machine running Ubuntu 11.10 on Live USB. Test on + a Ubuntu 10.04 machine shows no sign of bug, it doesn't not panic. - 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*)).
