Comment 16 for bug 194523

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
