No kernel newer than 2.6.5 seems to work for my SMP box these days.. :-/
On Linux 2.6.10-rc2, my ALI USB controller no longer works properly.
Specifically, ehci connection are slow (not usb2.0 high-speed). It seems that
the kernel thinks that my controller has experienced a fatal error. The
following "fix" to line 858 of ehci-hcd.c gets past that:
change
if (unlikely ((status & STS_FATAL) != 0)) {
to
if (0) {
Then, it more or less works, but you get tons of I/O errors when reading:
end_request: I/O error, dev sr0, sector 2712
Buffer I/O error on device sr0, logical block 339
end_request: I/O error, dev sr0, sector 2712
Buffer I/O error on device sr0, logical block 339
end_request: I/O error, dev sr0, sector 2712
Buffer I/O error on device sr0, logical block 339
end_request: I/O error, dev sr0, sector 2712
Buffer I/O error on device sr0, logical block 339
end_request: I/O error, dev sr0, sector 2712
Buffer I/O error on device sr0, logical block 339
end_request: I/O error, dev sr0, sector 2720
Buffer I/O error on device sr0, logical block 340
end_request: I/O error, dev sr0, sector 2720
On reconnecting devices I get strange warnings, like so:
usb 1-4: USB disconnect, address 2
usb 1-4.3: USB disconnect, address 6
usb 1-4.4: USB disconnect, address 5

(on high-speed devices, hubs and controllers)
but no oops'es, crashes or lockups. Just a kernel that doesn't work work :-/
I feel I'm so very close to having solved the last problem with 2.6.10-rc2,
and I would really like to use it. Any suggestions?
