New description:
I get the above error on Xscale platfrom with 2.4.31-uc0 kernel.
I use Revision: 1708, I changed the .inc file in order to make it compile
on xscale (as was mentioned on the mailing list) and I laso applied the
patch to hal/linux/ah_osdep.h which changes _OS_REG_WRITE macro.
Anyway, nothing helped and I still get kernel oops in ismod ath_pci
