Hi,

[1.] One line summary of the problem:

Kernel oops related to emulated(?) serial device using pl2303 and pppd.

[2.] Full description of the problem/report:

I get the following oops shortly after pppd begins using the ttyUSB0
device. After the case I cannot use ttyUSB0 and the pppd process sticks
in too (kill -9 is inefficient after the oops), so I have to reboot to
redial.

[3.] Keywords (i.e., modules, networking, kernel):

usb, serial, kernel

[4.] Kernel version (from /proc/version):

Linux version 2.4.22-grsec (buga@piccolo) (gcc version 3.3.2 20030908 (Debian prerelease)) #1 Thu Sep 18 21:23:04 CEST 2003
