1) Please _always_ keep the parisc-linux mailing list copied
on kernel bug reports.
2) Please send email in "text/plain" format.
I ignored everything you wrote in HTML.
3) Comments that follow are based on the Console output that you included.
(Thanks - that's what I really needed)

You will have to disable SCSI_PPA driver from your config.
It might be easiest to manually remove the driver from
the initrd.img file and from the /lib/modules on the root disk.
I looked at ppa_init() and it looks quite broken for hppa.
The problem is stuff like this:
static int ppa_byte_in(unsigned short base, char *buffer, int len)
"base" needs to be u32 (unsigned int).
parisc-linux needs more than 16 bits to represent an IO port address.
This _could_ work if the parallel port were under PCI Bus 0 _and_
no other garbage is in the top 16 bits of the register.

It's not just this. ppa and imm are pretty broken even on x86: they
don't use kmap to access the pio data, so they only work in memory from
ZONE_NORMAL ... this probably doesn't affect parisc since we don't have
a ZONE_HIGHMEM, however any READ_ command will go into the kernel's view
of the memory without cache flushing, so it's probable we'd get nasty
cache coherency issues.

That will not resolve your pb but as I recently encounter such warning and know now that it's usefull, I would also take care of
those messages. (may be simply check if all memory chips are pluged in correctly and 'in proper sequence')
Hth 2,
