Ferdy and me are also suffering a similar problem using 53c810
controller on AS2100. On our alpha, if you try to boot the installcd
using a 2.6 kernel you will see a lovely kernel dump.
2.6 kernel 53c810 driver seems to be completely broken for us, and
indeed, 2.4 driver works just fine.
After some investigations, i found (on red-hat alpha mailing list) they
patched 2.6 53c810 in some way for the next release of AlphaCore 2.0.
After unpacked the patches from red-hat kernel, I saw a lovely
linux-2.6.12-ncr810-alpha.patch which could be what we are looking
for. If you can give it a try and report the feedback would be c00l.
I'm installing a testing machine to work on this problem but still don't
have time to check if it works.

I think the problem comes from the kernel driver, udev/devfs have
nothing to do with this (imho).

2.6 SMP kernels are still broken on alpha. I think there are some people
mainly from red-hat trying to fix this at the moment. May be kloeri or
agriffis can tell us a bit more about this issue.

A stable gcc should be ready to compile everything!! you can use
3.4.4-r1 to compile all your system.
