Tried 2.6.30-6 kernels today. Uniprocessor parisc64 kernel behaves the 
same. parisc64-smp kernel has an additional crash:

Command line for kernel: 'root=/dev/sda5 HOME=/ console=ttyS0 TERM=vt102 palo_kernel=2/vmlinux-2.6.30-1-parisc64-smp'

Branching to kernel entry point 0x00100000.  If this is the last
message you see, you may need to switch your console.  This is
a common symptom -- search the FAQ and mailing list at parisc-linux.org
