Hi !
I've tried to get my 710 running with parisc linux.
I know there are problems with SCSI and LAN, so tried to find out.
The drivers both fail to call "pci_alloc_consistent()" and use memory from
__get_free_pages() instead.
Could it be that the problem is related to this ?
Regards Heiko Jakob

No, that is expected behaviour on older systems with non-consistent
memory. The problem appears to be with interrupt routing from the
scsi and lan chips to the cpu, and we don't have the documentation to
resolve that at the moment.

Thank you for your answer.
I almost forgot to say: HIL is also broken on the 710.
I guess there is nothing recently working on the 710 that needs to handle
with interrupts.
Could you tell me on which chip is the interrupt handling done ?
Is there something like a APIC ?

A custom HP chip, called ASP on the 710, I think.
