Bug#398360: Default 2.6 kernel image throws a "kernel BUG" when accessing a USB-Harddisk
Package: kernel-image-2.6.8-3-386
Version: 2.6.8-16sarge5
When accessing an external IDE-HDD connected via USB the kernel throws
an "kernel bug" message and
the access to the drive is delayed.
I am using a Debian 3.1 sarge installation without any backports or
kernel-patches.
The kernel in use is the one you get when you install Debian with "linux26".
Here is the exact error message, the first lines beginning with "SCSI
error:" are repaeted very often:
