Hi, guys! I'm verry sad. Since 2.2.5 I have a oopsin process swapper related to PPP.
[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
[5.] Output of Oops.. message (if applicable) with symbolic information resolved (see Documentation/oops-tracing.txt) ksymoops 0.7b on i686 2.2.12. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.2.13 (specified) -m /boot/System.map-2.2.13 (specified)

SMP kernel Cyclades card (Cyclom YeP/DB25 - 32 ports (8+8+16)) 3COM905B Cyclone ESS1869 sound card
[X.] Other notes, patches, fixes, workarounds: 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!
