Sorry it took so long to do further debugging... Anyway the System.map
says:

102ee3a0 ? parisc_hardware_description
1010ae98 T alloc_pa_dev

I do have an extra card (X25-card as far as I can remember) on expansion
slot. I recompiled the kernel with the "EARLY_BOOTUP_DEBUG" and here are
the results:

...
ext2_mount(partition 3) returns 0
