Public bug reported:
After upgrading to 2.6.31-17 I began having wireless problems. After
suspending, wireless would no longer connect. It looks like the phy has been
disabled. This was in dmesg:
b43-phy0: Radio hardware status changed to DISABLED
...and rfkill list showed:
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
The only way I found to re-enable wireless was to boot into BIOS and
turn it back on there.
I have found a better workaround though. Rebooting into 2.6.31-15
causes the issue to go away. That's why I filed this as a bug against
the kernel instead of going to the forums. It seems like this only
became a problem sometime after 2.6.31-15.
