2.4.17-rc1 kernel panic at boot

[BURJAN Gabor]

Hello,

I have a problem with booting 2.4.17-rc1 on a RS/6000 (43P-140), when
Vortex support is compiled into the kernel.

01:03.0 Ethernet controller: 3Com Corporation 3c905 100BaseTX [Boomerang]
        Flags: bus master, medium devsel, latency 32, IRQ 24
        I/O ports at 3f7ffc00 [disabled] [size=64]
        Expansion ROM at feef0000 [disabled] [size=64K]

Oops data:

1 warning and 1 error issued.  Results may not be reliable.

I tried older kernels (2.4.15, 2.4.16) too, the error remained.
