I looked into /var/crash but nothing is there and also that error doesnt show up now. That dmesg I posted before was from first run after install... But the lockups are here now again, but I dont have to killall anything, computer freezes for a few seconds, prints few messages to tty1 where i logged in and then works ok. However it happens more often than before and as far as i can tell only when some program is writing to hda (simple rm in gnome terminal, closing gedit or gaim). Here is another dmesg, the ata1: and sda: messages are printed to tty when the laptop hangs.
