Hello Clem,
I am experiencing exactly the same problems with PCI peripherials on Au1500 with kernel 2.6.20.1, now I am trying 2.6.20.3 but I have few hopes. Kernel version
2.6.17.14 instead seems to be ok.
Perhaps sometime someone with better knowloedge than me will fix this issue, since I am truly a newbie.
I am also trying to make out Sil3512 work with sata_sil, in kernel
2.6.17.14 it hangs when probing the dis. Exactly which Sil controller are you using? Do you have an EPROM on your controller? It is present in the PCI reference card but our engineer decided to go without it. I am not sure it has been a good idea..
