Look for HPMC's. The console can't keep up with the kernel in general.
When an HPMC occurs, some of the output can get stranded.

I would add "initcall_debug=1" to boot parameters. See kernel/main.c.
Possible add a mdelay(100) after each initcall.

Since Tulip configured properly, I'm going to assume PCI resources
were properly assigned and all PCI Busses enumerated. PCI support
shouldn't be any different than for other PAT PDC machines.
