I installed Mandrake 9.2 yesterday. The installation went fine. I still got KDE to crash after waking up from suspend (to RAM). The second time I tried it I got a Kernel panic.

I remembered seeing information that PCMCIA and sound may mess up the system, so I turned off the 'pcmcia' and 'sound' service. After a reboot everything works just fine - no crashes or anything :)

The sound is still working since ALSA is running. What is the 'sound' service used for? Is it for OSS? Is there a comprehensive list somewhere that tells me what different Linux services are doing? The help/info in Linux is not always clear...
