I tested on todays wireless-testing, aka v2.6.30-rc5-23297-gbf2c6a3.
Somehow, it triggers an OOPS
Function: req_reg_info_regd
Process: modprobe
Call trace:
wiphy_apply_custom_regulatory
ath5k_regd_init
ath5k_reg_notifier
ath5k_pci_probe
...

The kernel then hangs later on in the boot process. It responds to
SysRq, but does not echo normal keypresses. SysRq+P shows that the
kernel is in the idle task. I left it for three minutes, but I didn't
get any trace from the hung task detector or soft lockup detector.
At first I thought it must be a problem with wireless-testing.
However, it went away when I eventually tried un-applying the rfkill
rewrite patch.
Thanks
Alan
