I did. The weirdest bug ever. Turns out it was the atheros card fault. The machine was more or less stable with a ping running in the background. Otherwise, it would crash - several times a day with 32 bit userland binaries, once every 2 days with 64 bit userland binaries. Like you, no log message - regardless of what log system I used, or even remote logging.

I checked so many things it took me several month to figure it out -- and since none of the recommended atheros kernel options helped,  I could fix that only by replacing the card with a apple branded atheros - ar9380 if I remember correctly.

Try to remove all tthe ath9k modules and use your computer as you normally do. See if you have any crash.

BTW I was also having opengl related freezes (100% reproductible with xlock), fixed by adding NoDRI to xorg.conf

Hi Again,

Sorry for the inconvenience of having two separate mails. I am currently on a handheld and I am already missing my X200 Keyboard...

About the freezing: One can still see the last state of the deskop on the screen, but the system does not respond to input or ping. Also I can't find anyting in the log files I checked, which makes debugging extremely difficult. I tried different live systems as well as changing the RAM (i switched one original 2GB for one crucial 4GB -- so the second slot was always empty) and i still see the freezes. Again, has anyone seen something similar?
