Then on the same kernel you have vol_id stuck. The obvious explanation is that vol_id needs to take a lock that was take by the dead vol_id. This is an IDE problem, not a USB problem. It makes little sense to debug a kernel that already has oopsed and I know next to nothing about the IDE layer. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=326387#c10 --- Comment #10 from Oliver Neukum 2007-09-21 02:23:53 MST --- Your log shows the device being mounted: Sep 20 14:16:07 scherben hald: mounted /dev/sdb1 on behalf of uid 1000 hence the block device node must have existed. It shows a disconnect a little later. Please recapture the log and just capture the portion of attaching the device. Clear the buffer with dmesg -c, then attach the device, wait for a few seconds, then use dmesg to capture the log. Don't disconnect before you capture. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
