Hi,

[1.] One line summary of the problem:

System hang under X

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

Working with Netscape under X the system hangs complete.
No mouse or keyboard anymore, I must hit the reset button.
After booting I see a oops in /var/log/messages.

This happened twice before with a clean 2.3.7, after the
Andrea patch for 2.3.7 it stopped. Now with a clean 2.3.8
it is back again.

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

Linux 2.3.8 with gcc 2.7.2.3
