I have some problems with this hardware, too. Maybe I can provide some useful bugreports - I'd gladly do some tests with the 2.4.x kernels if someone is interested (I only tried 2.4.19 and 2.4.20 with this hardware so far).
I have a Tyan S2466N-4M (Tiger MPX, Chipset AMD 760MPX, 762, 768), 2x Athlon MP 2000+, 512MB Reg. ECC SDRAM 2-3 IDE drives and a DVD-ROM on the onboard channels DMA support enabled (I don't like to disable this, because when I copy over 100MB from the DVD to a harddrive with DMA disabled the cpu-usage wents well above 50% and then the machine _freezes_.)
With 2.4.19, the power-switch didn't work after shutdown (It works now with 2.4.20). Automatic power-off (halt -p) doesn't work with neighter 2.4.19 nor 2.4.20.
With "AMD 76x native power management" I experienced freezes under X11 when the system was idle for about 30 min that usually went away when I typed on the keyboard. Using the (USB) mouse had no effect. But I had no problems at boot-time.
Thomas.
