This happens me three times this week. Can somebody help me to prepare trap for it and find what has happens ? I'm not kernel guru and not very familiar with ppc assembler. Thanks. Tomas Hardware, Software and Symptoms: HW: PPC G3 beige, 160 MB of memory, (CONFIG_HIGHMEM off) SW: Debian 2.2 unstable, kernel 2.2.5-pre1 (gcc 2.95.4) Do kernel debug options included ( sysmon,....) Also happened with kernel 2.2.4-x. Loaded machine (>1)( running package instalation or compilation). Then dies a wmtop (Window Maker top). It is not suid program. In this moment apperars in syslog Oops: kernel access of bad area, sig: 11 NIP: C0058B90 XER: 00000000 LR: C00563A8 SP: C87C7D50 REGS: c87c7ca0 TRAP: 0300 MSR: 00009032 EE: 1 PR: 0 FP: 0 ME: 1 IR/DR: 11 DAR: 00000004, DSISR: 40000000 TASK = c87c6000[18224] 'wmtop' Last syscall: 3 ....... than any attempt of process listing fails (never finish and stay hooked) and every time there is three proceses at the end of listnig: 24459 ? S 0:00 /USR/SBIN/CRON 24460 ? S 0:00 /bin/sh -c if [ -x /usr/sbin/exim -a -f /etc/exim/exim.conf ]; then /usr/s 24461 ? S 0:00 /usr/sbin/exim -q Yes, exim mailer is suid ;-( Load measurement is still possible but, shows number of frozen processes. Any ideas where is a mistake or how to solve it? Just happen again.
