Re: More on the 760MP

[Willem Riede]

I'm not having much luck with this :-(

I also have a Tyan Tiger MP, and have built a 2.4.10-ac12 based kernel
for it. Actually, I modified the Rawhide kernel SRPM to use linux-2.4.10
and the ac12 patch, as I run ext3 and software raid installed by RedHat's
Roswell beta, and I need to stay compatible with that; then made and
installed the athlon-smp RPM. 

It contains 2.6.1 for i2c, and I generated the patch for lm_sensors
2.6.1 to replace the older patch for lm_sensors in the SRPM.

The i2c-amd756 module hangs my kernel too, but you seem to have it
work without it? I don't get anything detected without i2c-amd756. 
This is what the log messages say (but I have to reboot to read them):

Oct 14 16:17:16 linnie kernel: i2c-amd756.o version 2.6.1 (20010830)
Oct 14 16:17:16 linnie kernel: i2c-dev.o: Registered 'SMBus AMD7X6 adapter
at 80e0' as minor 1
Oct 14 16:17:16 linnie kernel: i2c-core.o: client [W83782D chip] registered
to adapter [SMBus AMD7X6 adapter at 80e0](pos. 0).
Oct 14 16:17:16 linnie kernel: i2c-core.o: client [W83782D subclient]
registered to adapter [SMBus AMD7X6 adapter at 80e0](pos. 1).
Oct 14 16:17:16 linnie kernel: i2c-core.o: client [W83782D subclient]
registered to adapter [SMBus AMD7X6 adapter at 80e0](pos. 2).

Or is it this module (i2c-amd756) that you say must be included in the 
kernel to make 'it' work (English is so ambiguous :-))?

One more question if you don't mind: do you (still) have to first
read the sensors in the BIOS before booting? If I do that, for some
reason, I don't get my grub boot screen after exiting setup, instead
the board tries to boot off the lan; I ctrl-atl-del out of that, and 
then things are back to normal, but that soft reset probably undid
whatever reading the sensors in the bios changed :-(
Any other settings in the bios that matter?

Thanks, Willem Riede.
