>Description:
Upgrade from 7.1-RELEASE to 7.2-RELEASE prevents system from booting. It stops with message:

I have submitted earlier a PR about the non-working ath (yeah, sorry for that garbage at the end):

http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/116444

Pls tell me if you need more output.
>How-To-Repeat:
Upgrade to 7.2-RELEASE and boot.
>Fix:
For the moment, disabling ath in GENERIC makes the system boot:

# grep ath /usr/src/sys/i386/conf/GENERIC

#device         ath             # Atheros pci/cardbus NIC's
#device         ath_hal         # Atheros HAL (Hardware Access Layer)
#device         ath_rate_sample # SampleRate tx rate control for ath
