The megaraid driver in 2.2.18 doesn't work with MegaRaid 434 cards.
I've tried it on 2 different systems. Using 2.2.18pre11 with the
megaraid.[ch] from 2.2.17 works just fine.

I've only been able to test with SMP systems though - perhaps this is
a uniprocessor / SMP problem ?

Excerpt from the bootlog of 2.2.18pre11 vanilla:

[normal bootup]
megaraid: v1.11 (Aug 23, 2000)
megaraid: found 0x8086:0x1960:idx 0:bus 0:slot 11:func 1
scsi0 : Found a MegaRAID controller at 0xd0002000, IRQ: 18

[hangs indefinitely]

And from the bootlog of 2.2.18pre11 with the 2.2.17 megaraid.[ch] :

[normal bootup]
megaraid: v107 (December 22, 1999)
megaraid: found 0x8086:0x1960:idx 0:bus 0:slot 11:func 1
