[1.] One line summary of the problem:
OOPS is process syslogd related to tty/ppp/cyclades
This pissed me off since 2.2.5 at least.
[2.] Full description of the problem/report:
After 30 minutes / 12-20 hours (first run / second run) the kernel oopses.
No big load. It hangs rock solid. Magic sysrq "works" but no unmount.
[3.] Keywords (i.e., modules, networking, kernel):
ppp tty cyclades
[4.] Kernel version (from /proc/version):
Linux version 2.2.13 (root@marte) (gcc version 2.7.2.3) #3 SMP xxx xxx xx
xx:xx:xx EEST 1999

Reboot.
I'll try to investigate the cause.
If someone will try to find the bug, I apreciate if send me a mail to tell
me that.
Thank you!
