Bug#299553: kernel-image-2.6.8-2-686: plugging in disk freezes /proc/bus/usb
Package: kernel-image-2.6.8-2-686
Version: 2.6.8-13
Severity: important
When I plug in a LaCie 40Gb USB 2.0 disk, which is a SCSI disk
transported over USB, the entire USB subsystem seems to freeze.
Specifically, cat /proc/bus/usb/devices never exits,
usbview never puts up its window, etc.
These process are unkillable via
sudo kill -9 NNNNN.
On the initial plug-in, I see this in /var/log/syslog:
Mar 14 22:32:46 gpk kernel: usb 2-2.1: new full speed USB device using address 5
Mar 14 22:32:47 gpk kernel: scsi1 : SCSI emulation for USB Mass Storage devices
Mar 14 22:32:47 gpk usb.agent[30158]: usb-storage: already loaded
(USB storage is already loaded because I plugged in a different
disk earlier, and it worked very nicely.)
No disk appears in /dev (using udev).
Unplugging the disk does not cause any lines to appear in
/var/log/syslog, nor does plugging it in again.
Here are some possibly relevant lines from ps -e -f:
