I'd run an actual RAM test and also run the mfg's HD diagnostic for starters

Assuming that this is related with the previous IDE error in the log, this could indicate that the disk controller has locked up. Google says that this can happen with certain buggy nVidia SATA controllers, but you didn't tell us anything about the hardware in your system. Regards, Clemens
