The hardware: SuperMicro H8DME-2. Four 1Gbyte DDR2-667/533/400 Registered ECC SDRAM sticks from
Crucial.
Two Quad-Core AMD 2378 2.4 GHz Processors. Onboard video. One SATA disk. One PATA DVD-ROM reader. NULL modem serial cable from COM1 to COM1 on another PC.
The details: When booting coreboot, nothing happens for about 45 seconds. Then the fans speed up to high and some messages start appearing on the serial line. These messages print rather slowly (maybe 1 second/message). They are:
coreboot-4.0-r5521M Wed May 5 10:53:42 EDT 2010 starting... *sysinfo range: [000cf000,000cf730] bsp_apicid=00 Enabling routing table for node 00 done. Enabling SMP settings (0,1) link=00
This looks like the bootup code for gen f Opterons. It doesn't look like the h8dme has a fam10 variant yet, which is what you need for the 2378 CPUs.
Thanks Arne! I'll have to figure out how to proceed from here.
On a side note, it _looks_ like the slowdown might be due to the udelay unification. Still bisecting.
I'm surprised you found a revision that works, since it has never supported fam10. I think it would be more fruitful for you to look at one of the boards that has both fam10 and k8 support, and try to put together an h8dme_fam10 port.
Thanks, Myles
