Hello,

Thanks for your investigation, it's clearly useful!

The serial number doesn't exactly match, so there is little surprise I
guess.

Ok. That's odd as there is no infinite loop there :)

Oh? That's not supposed to happen, as the code shows as well as callers
of these. Could you investigate in that direction?

That's odd too, could you check the value returned by
match_pci_cmd640_device and the value of cmd640_key?

Could you check where in the i loop and which instruction of the
get_cmd640_reg_pci1 loop exactly?

Indeed. I guess your controler is a SATA one. You need to enable legacy
IDE/ATA emulation in the bios for gnumach to be able to use it. If there
is no such option, you're hosed :/

Thanks again,
