Stuck num-lock and disabled touchpad when waking from sleep
Add i8042.nomux to the bootloader's kernel parameters. On some machines (at least model 076831G) the touchpad and keyboard may suddenly stop working, even after several hours of uptime. No error is found in syslog. To resolve this issue replace i8042.nomux with i8042.reset option. This is valid for kernels starting with version 2.6.18.

CPU Fan stop working/constantly working after resume from suspend to disk
Sometimes after resume from suspend to disk CPU Fan stucks at one state: it constantly working (isn't dangerous, but annoying), or it's always stopped (dangerous, can cause overheat). Bug filed at kernel bugzilla and ubuntu launchpad.

It seems that it's BIOS bug, and there's no solution at the moment.

Soundcard not working with Internal Modem disabled
You have to enable the "Internal Modem" in the BIOS settings to get sound.
