Package: kernek
Severity: important
I just rebooted after installing updates (probably a kernel since reboot was required), and now my pl2303 usb serial dongle stopped working.
It's quite important for me to have this working. I'll probably reboot into a older kernel if possible until this is fixed.

Marking accordingly. Thanks for checking.
Can you reproduce this with 2.6.33-1~experimental.4 from
<http://snapshot.debian.org/>? (I have a vague hope that
v2.6.33-rc1~310^2~43 or some nearby change might fix this.)
Curious,
Jonathan
