Hm, the BIOS seems to behave nastier than expected -- looks like it reprograms DPLL but doesn't save the initial f_CNT (needed to determine the PCI clock). Well, I know that it always sets DPLL to 50 MHz, no matter what's the chip, so will try to work around this... :-/ > but the rest is the same ... This (otherwise incorrect) patch should eliminate the oops on HPT372: http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.17-rc1/2.6.17-rc1-mm2/broken-out/hpt366-fix-segfault-during-init.patch The clocking however will remain invalid...
