[Bug 194523] Re: computer frozen

[jyks]

Hardy Beta (with all latest updates) on my Compaq v3000 seems to have this problem. So you are not alone!
The laptop randomly freezes mostly resulting in a hard reboot. But recently i  just  switched off the wireless antenaa and after a few minutes it starts responding! I have been able to reproduce this behaviour atleast twice. 

Driver Versions:
nvidia-glx-new: 169.12+2.6.24.11-12.31
b43 with broadcom-wl-4.80.53.0 firware

dmesg after/before the freeze [ freezetime stamp around 356] :
