Hi all,

I could actually hear this happening to the hard disk - but thought it was my imagination.

Linux windy 2.6.32-5-amd64 #1 SMP Wed May 18 23:13:22 UTC 2011 x86_64 GNU/Linux

anybody have any ideas ?

disk seems to be ok, not making any funny noises - well unless it resets. I can actually hear it !

I seriously doubt this is the MB or disk. This behavior started with testing...

This problem has shown up in the kernel before.

Not sure how to try and reproduce it.

Well, time to reboot with 2.6.39 and see what happens.

Scenarios always come in sets of three:
best case, worst case, and just in case.

doubt it. hasn't happened since I first found the problem - almost 2 days.

looking through old kernel bug reports this program has reared it's ugly head more than once.

one person reported that it was reproducible when playing video.

I am almost certain that it was coincident with a web page I had up, just not sure which one..

probably flash related being that flash is evil.
