Ferdy and me are also suffering a similar problem using 53c810 |
| 30 |
controller on AS2100. On our alpha, if you try to boot the installcd |
| 31 |
using a 2.6 kernel you will see a lovely kernel dump. |
| 32 |
|
| 33 |
2.6 kernel 53c810 driver seems to be completely broken for us, and |
| 34 |
indeed, 2.4 driver works just fine. |
| 35 |
|
| 36 |
After some investigations, i found (on red-hat alpha mailing list) they |
| 37 |
patched 2.6 53c810 in some way for the next release of AlphaCore 2.0. |
| 38 |
After unpacked the patches from red-hat kernel, I saw a lovely |
| 39 |
linux-2.6.12-ncr810-alpha.patch[1] which could be what we are looking |
| 40 |
for. If you can give it a try and report the feedback would be c00l. |
| 41 |
|
| 42 |
I'm installing a testing machine to work on this problem but still don't |
| 43 |
have time to check if it works. |

I think the problem comes from the kernel driver, udev/devfs have |
| 50 |
nothing to do with this (imho). |

2.6 SMP kernels are still broken on alpha. I think there are some people |
| 59 |
mainly from red-hat trying to fix this at the moment. May be kloeri or |
| 60 |
agriffis can tell us a bit more about this issue. |

A stable gcc should be ready to compile everything!! you can use |
| 68 |
3.4.4-r1 to compile all your system. |
