There is no such thing as BIOS on this MPC8540 embedded system.
I guess he is also using some bootloader which just gives full
control to the linux kernel.

Correct, it's the U-Boot boot loader.

Florian:
Check the IP route chache flushes, as Eric mentioned.
I'm working on the MPC854x as well. If you send me your scripts,
I can give them a run here to gather more information.
(I'm about to update my kernels here)

Thanks, the rhash_entries argument seems to have cured the problem.

Cheers,

Florian
