Hi!

I see this in syslog:

CPU: Before vendor init, caps: 0183fbff c1c7fbff 00000000, vendor = 2 Enabling disabled K7/SSE Support.
CPU: L1 I Cache: 64K (64 bytes/line), D cache 64K (64 bytes/line)
CPU: L2 Cache: 256K (64 bytes/line)
CPU: After vendor init, caps: 0383fbff c1c7fbff 00000000 00000000 Intel machine check architecture supported.
Intel machine check reporting enabled on CPU#0.

CPU:     After generic, caps: 0383fbff c1c7fbff 00000000 00000000

Why _Intel_ machine check? And why it says CPU: After vendor init twice? [This is 2.5.6-acpi...]

AMD supports the intel machine check on Athlon

SMP kernel ?
We init the boot CPU twice on SMP iirc.

Unless I made mistake, it was UP kernel.

Same reason the Athlon has Intel style MTRRs.
Though digging through the docs the last day or so, the MCE isn't 100% compatable. I'll work on this sometime soon.
