Update

I've been trying to reproduce this bug all morning, and could not 
reproduce it without firefox running. I then saw with dmesg that the 
flash plugin had crashed:

[ 2170.872049] npviewer.bin[9053]: segfault at 0 ip f6dc9348 sp ffd3e788 
error 4 in libflashplayer.so[f6d2c000+66b000]

This would explain why it can take several days between me experiencing 
the bug, but it doesn't explain the mixed up timestamps in kern.log

Even if flash/npviewer is at fault, IMHO it shouldn't cause microlockups 
that I experience

regards, Richard
