I'm aware this way all ports actively using `mm->context' needs to
be changed but the change is certainly a no-brainer... OK?
My problem is that I don't want to typedef it to a structure, this

I got you was proposing that but once we change it I preferred to use a generic

Compile again with the following patches (these are against 2.4.0-test12,
but those in arch/alpha/kernel/core_cia.c should work against test10/11
as well).

Yes. I have tried it on an ES40 with 16 Gig of ram, and it boots just fine.

In the arch/alpha/kernel/pci_iommu.c change

Perhaps this will give us more info.

Ivan,
I have tried test12-pre3 with and without your patch, it fails in the same
way.
The Qlogic SCSI controller continues to fail if we have >1 gig in the machine.

Any ideas? (Or patches that I can test... ;-) )

test12-pre2 crashes at boot on my DS20. This patch workaround the problem
but I would be _very_ surprised if this is the right fix :) It's obviously not

Ivan,
We dug a little deeper, and think that we found the problem.
The error occurs if we have over 1024 MB of memory in the machine.
If we have less than 1024MB, the machine behaves correctly.

Hi All,
Qlogic SCSI support seems broken on 2.4.0-test11 on a Miata (Digital Personal
WorkStation 600au).
When starting up, we get a machine check after initialing the qlogic SCSI code.
Using the Alpha kgdb, we figured out that the code is dying in scsi_wait_request().
Here's the backtrace:
