Actually I had offered to provide a summary of similar reports from the web with no takers, I can still provide that to somebody if it is useful. I had run memtest overnight with no errors, I use DRM etc.. The reason to post this is that very first line in the syslog entries related to this error seems to be different than before. {It is typically is kernel BUG at mm/rmap.c or sth similar}. Thanks, Jay P.S. I am getting this error once in 3 days on an average (based on grep of moths worth syslog) so I might have dubious distinction of being more repeatable. May be it confirms Hugh's suspicion of hardware misbehaving but I am not ready to accept it yet :-) #### Feb 26 09:37:03 localhost kernel: mm/memory.c:110: bad pmd 00000500.
