Same here on a neq Thinkpad T61 with Ubuntu 8.10 clean install, all
updates as of 21 Nov 2008. I had the laptop running idle for about half
an hour and when I returned to it it had frozen and the laptop lights
for Wifi, Bluetooth (and maybe some others) were flashing fast. The logs
are huge and full " bad: scheduling from the idle thread!". Maybe there
are other errors in there, but I've no clue what to look for in these
huge files. Here's were it all started:
