Happened to me the third time now in the last couple of months, always with different Linus kernels (plus ACX100 wireless module from Denis Vlasenko's snapshots) all hanging off an up-to-date FC4, all built with latest stock GCC; this last is: [root@incident ~]# cat /proc/version Linux version 2.6.14-rc5-git5 (asuardi@incident) (gcc version 4.0.2) #1 PREEMPT Tue Oct 25 14:32:46 CEST 2005 Symptoms: startx at the command prompt gets the blank screen, then... nothing. Keyboard is dead (CapsLock doesn't get its led lit), no VT switching works. Box is still reachable via ssh through its wireless network card, all looks OK except for X running and piling up CPU time, and apparently untraceable (pstack, strace hang trying to attach it) and unkillable (kill -9 doesn't kill it). I took a couple of SysRQ 't' dumps via the /proc/sysrq-trigger facility and the outcome is attached - actually it's a full messages log, startup to reboot. Exact sequence this time: 1. boot 2. insmod 0.3.17 acx driver -> notice I can't contact my wireless AP 3. rmmod it, insmod 0.3.16 driver -> notice I am an idiot, plug in the wireless AP power cord 4. rmmod 0.3.16, insmod 0.3.17, iwconfig wlan0 up 5. switch to VT2 (Alt-F2), login as non-root, run startx <blank screen, dead keyboard> 6. ssh in from remote box, take SysRQ dumps, reboot If anyone has an idea on what to do to try and reproduce and/or debug further, that'd be cool. Box is a Dell Latitude C640 laptop, [email protected], 1GB RAM, with a USR2210 802.11b wireless PC Card; video card is a Radeon 7500 M7 LW. Thanks in advance, ciao, --alessandro "All it takes is one decision A lot of guts, a little vision to wave Your worries, and cares goodbye" (Placebo - "Slave To The Wage")
