Hi!
I'm trying to upgrade the kernel in a Samba fileserver from a custom-
compiled 2.6.8.1 to a stock Debian 2.8.12-1-powerpc and running into
an issue with my Sonnet Tempo ATA/100 [The card is a rebranded
FirmTek UltraTek/100 which is _actually_ a Promise PDC20268 with Mac-
bootable firmware ROM]. I'm getting the following BUG() output
[NOTE: This was hand-copied from the screen after panic, so there may
be typos despite me being careful to avoid them]:
PDC20268: IDE controller at PCI slot 0001:11:02.0
PDC20268: chipset revision 2
PDC20268: ROM enabled at 0x80090000
PDC20268: 100% native mode on irq 52
ide2: PDC20268 Bus-Master DMA disabled (BIOS)
ide3: BM-DMA at 0x1408-0x140f, BIOS settings: hdg:pio, hdh:pio

This comes while the Debian initrd is modprobing various drivers.
The working log from my older 2.6.8.1 kernel is appended. Thanks for
any advice you can give! This system is somewhat difficult to test
new kernels on as it is in production and a 5 hour drive away, but
I'll try to do what I can.
Cheers,
Kyle Moffett

Do you have any other ideas WRT this bug? I've been browsing around
in the code a bit, and I plan to try diffing my 2.6.8.1 version of
the files against the latest Debian to see what changed, although I
suspect it will be a relatively fat hunk of changes. Thanks for your
help!

Nope. The lspci output looks perfectly normal. I looks like a mixture of
issues with BM DMA being disabled for a reason I haven't figured out and
then the code crashing because it doesn't like BM-DMA being disabled ...
Again, best is you pour printk's all over setup-pci.c and ide-dma.c to
figure out what's going on...

BusMaster-DMA definitely should be enabled on that card. After a lot
of looking through icky IDE code, I've determined that the reason for
the crash is that if there is a "mate", or another IDE bus on the
same card, then hwif->dma_master is set to hwif->mate->dma_base on
the secondary channel. Since DMA explicitly wasn't enabled on the
primary channel, hwif->dma_master on the secondary is 0 even though
dma is enabled, and therefore we hit that BUG().
Therefore it seems that the only issue is ide_get_or_set_dma_base is
returning 0 when it should return a valid DMA base. In that
function, the only ways that function can even theoretically return 0
without printing any weird error messages is "if (hwif->mmio)" or "if
(hwif->mate && hwif->mate->dma_base)". The latter can't happen
before hwif->mate is set up (since the problem is while initializing
the primary). Could hwif->mmio be nonzero somehow? The only drivers
that seem to set it are pci/sgiioc4, pci/siimage, ppc/pmac, and a
couple misc arch drivers.
I see a couple theoretical possibilities:
* hwif->mate and hwif->mate->dma_base are set for the primary
while still initializing it (before any secondary is set up.
* hwif->mmio is set somehow even though it shouldn't be, is the
value ever pre-initialized to 0?

I wish I could but the machine is remote and in-production, so it's
hard to have time to do much with it. I'm trying as best I can to
walk through the sources by hand, specifically with regards to
changes between the two. I'm hoping I can come up with a good enough
guess by Thanksgiving, so that when I have a week near the server to
test things out I can make significant progress.
Cheers,

I have yet to see any problem, however complicated, which, when you
looked at it in the right way, did not become still more complicated.

Maybe there is some fighting going on between ppc/pmac.c and that driver
over the hwif's and you end up with mmio inadvertently set ?

This is verified by adding printks to the code. This is exactly
where it crashes.

With heavy printk debugging, I have identified that the hwif->mmio is
getting set to 2 somewhere (even though the PDC driver never touches
it). I added an extra line in the PDC init code to explicitly zero
hwif->mmio, but I get the same result, so something else is mashing
on the PDC hwif.

This is the only possibility that I can think of, but I'm having a
hard time getting enough lines of pre-BUG output. Is there any way
to turn off the BUG() lines and just show the printks before that point?

There is a patch from Thibault that fixes it, it should be in 2.6.15-rc2
Ben.
i have a promise controller and it fails too, but only some times (never
during startup).. i get the following errors:
hdf: dma_intr: bad DMA status (dma_stat=75)
hdf: dma_intr: status=0x50 { DriveReady SeekComplete }
ide: failed opcode was: unknown
hdf: dma_timer_expiry: dma status == 0x60
hdf: DMA timeout retry
PDC202XX: Primary channel reset.
hdf: timeout waiting for DMA
and i know for a fact it isnt the indidual controller, as i tried with 2
other brand new ones, and i know it isnt the drives/cables/computer,
since i tried switching it all around, and it keeps happening.
if it does this while reading/writing the system hardlocks..
i wrote promise technical support, which said it could be caused by
sharing interrupts, so i checked, and it did share with my NIC, so i
switched to another pci slot, and now it has its own interrupt, YET it
still keeps doing this..
i would greatly apreciate any help
