0% here. Admittedly I have only one VIA box and only as of this weekend but
it works great with all kernels tried. [Epox 8KTA3 mobo, KT133A chipset
running 266MHz FSB and 1.33GHz Athlon Thunderbird, PC133 CL2 RAM from
Micron, active PFC power supply, BIOS setup to the fastest settings it
allows me to set it to while stayin in spec (i.e. no o/c of CPU or
busses!), IBM Ericson ATA100 41GiB HD attached to the VIA controller].

Tried kernels are 2.4.4-4GB (from SuSE 7.1 binary install Pentium
optimizations I believe), 2.4.8 and 2.4.8-ac1 (the latter two both compiled
with Athlon optimizations) and the system is absolutely fine. bonnie
scores >30MiB/s (in mostly 34-39 MiB/s) on intelligent read/write tests
with DMA enabled and a working set 2x size of RAM (i.e. 512MiB test size on
256MiB RAM). Even when using fsync after every operation i/o speed is
almost unaffected (it drops a bit but only by about 1-2MiB/s).

Copying 15 GiB of data from one partition to the other on the same disk
worked fine. Compiling kernels works fine (Admittedly it only takes just
over 3 minutes to compile the kernel with make -j 2 bzImage, so it's not
too much of a stress test).

Oh and the VIA AC97 audio codec seems to work beautifully, too. As does X
(both 3.3.x and 4.0.3) is fine, too. (I use an ancient ET6000 PCI gfx card.)

So, basically no problems here. I was quite worried about buying a VIA
chipset but now it seems like a great buy. (-:

The only thing that's slightly annoying is that during boot three of the
PCI resources from the VIA chipset are reported as "unknown, treating
transparently" (or some simillar msg), don't have box handy to say what
they were exactly... if anyone is intersted in exact messages I can provide
dmesg + lspci -vvv output once I get home tonight.

Or alternatively buy quality components that other people have tested under
Linux with kernel 2.4...
