2) partitions:
/	ext3
/var	reiserfs

After the reboot I've checked the reiserfs partition and found errors
fixable only with "reiserfsck --rebuild-tree".


3) memory corruption?
With this PC I've experienced sporadically memory corruption many months
ago... but they are gone away disabling Memory Interleaving in the BIOS
(tested with memtest86+). Maybe it only fails less often...


4) Frequency scaling: the only thing I've recently enabled is frequence
scaling (with "ondemand" governor).
