I don't have my lm_sensors source handy right now, but I wanted to reply so perhaps you or someone else could look into this... I notice that the adapter is registered at address 6000. That's a bit of a strange isa address. I believe that the original ISA bus only has I/O addresses up to 3fff. Anything above that is either an alias or a PCI bus address. Perhaps there is a test in the ISA write function that makes sure the address you're attempting to write is in the range: 0-3fff or less and if not, returns an error. If 6000 is an alias, then the "ISA" address would have been 2000... I wonder why the VIA686A driver is looking for address 6000. Perhaps that came from a PCI register programmed by the BIOS? If so, then the VIA686A is really a PCI device and we need to generalize the isa driver's notion of I/O address space for PCI devices... :v) David wrote: > On Sunday 22 June 2003 03:44 pm, you wrote: > >>Well, the patch is either doing it's job or you didn't have the problem the >>patch was designed to fix.
