Everytime I resume my laptop from suspend mode, apmd oopses, causing ALSA to get very upset. Symptoms are:
* (not important, but funky) Screen remains blank until I attempt to switch to a different VC. Then all of a sudden XWindows appears, even though keyboard input goes into whatever tty I supposedly switched to. Hitting return causing the display to shift left an inch or so, wrapping around to the right side. This is fixed by "switching back" to the X's VC. * I get an artsmessage dialog box saying "Sound server fatal error: cpu overload, aborting". * The icon for klaptop disappears, although the system tray still leaves space for it. * Sound stops working until I reboot. Restarting ALSA fails ungracefully: # /etc/init.d/alsa restart Storing ALSA mixer settings ... done. Shutting down ALSA (version 0.9.6): /etc/init.d/alsa: line 166: 1103 Segmentation fault $rmmod $i >/dev/null 2>&1 done. Starting ALSA (version 0.9.6): ALSA appears to be compiled statically. Restoring ALSA mixer settings ... failed The tail end of /var/log/syslog is attached. It has two oopses in it: one from apmd, the other from rmmod.modutils (from the alsa restart). I'd appreciate any advice on things to try or documentation to read. Thank you! Regards, Neil
