O I'm counting on kmalloc to return a cache aligned buffer. I found
some reason to think it does, but I don't remember offhand what that

to be both physically and virtually contiguous, I was tempted to just

I hadn't considered that approach due to the way the ata_port is allocated:
libata-core.c:
host = scsi_host_alloc(ent-sht, sizeof(struct ata_port));
hosts.c:
struct Scsi_Host *scsi_host_alloc(struct scsi_host_template *sht, int
privsize)
{
shost =

I tell you what ... find me a parisc box that actually has IDE and we
might have told you ...
The NS87415 variant IDE has been tested on parisc and didn't blow up -
must just be lucky.
(actually, the pa8800's have IDE CD's on a cmd640 chip, but that oopses
on boot for no reason we've tracked

Actually, it's only a specific class of machines:

I wonder if this may be what I am seeing with the Si3124 on my Alpha
based setup.
I'm not sure if Alpha meets all the criteria, but the thing refuses to
recognize any drivers when they are connected and I see what are
supposed pci parity failures.
maybe not ...
