Subject: hpt366 kernel panic on EPoX 8K9A3+ fix (?)

[please cc:]

Hello,

with the 2.6.0-test3 kernel, hpt366 still does nothing else than kernel
panic on my machine. However, I found that with my EPoX 8K9A3+, the 0x78
(frequency) register of HPT374 has values in the interval of 0x9B..0x9E,
although the FSB is set to 133MHz and PCI should be at 33. Then, in
init_hpt37x, the execution usually goes thru the "freq < 0xb0" branch,
which doesn't do the pci_set_drvdata stuff. Later, the frequency
detection loop fails because hpt374 internal PLL isn't supported.
However, changing the respective branch to

} else if (freq < 0xb0) {
pll = F_LOW_PCI_40;
if (hpt_minimum_revision(dev,8)) {
pci_set_drvdata(dev, (void *)
thirty_three_base_hpt374);
printk("HPT37X: using 33MHz PCI clock\n");
}
} ...

made the driver work, although I didn't have time to test it (just
mounted the disk and copied a few files).

Regards,
