 Hi again,
 
 following up on my 3 months report... With a bunch of recompiles I have
 managed to pin down the cause:
 
 -CONFIG_PATA_CMD64X=m
 +# CONFIG_PATA_CMD64X is not set
 
 Enabling CONFIG_PATA_CMD64X module breaks booting both with 2.6.32.21
 and as well with the most recent 2.6.35.4.
 
 Is drivers/ata/pata_cmd64x.ko needed for any HPPA systems? Can we
 perhaps disable it from the kernel config again?

I believe cmd64x can be disabled.
I don't believe cmd64x PATA is built into any PA-RISC system.

cmd680 PATA driver is needed for C8000:
http://www.spinics.net/lists/linux-parisc/msg02761.html
(More info on C8000 http://www.openpa.net/systems/hp_c8000.html )

At one point, we might have thought c8000 had the same CDM649 PATA
controller as it's IA64 cousin, zx2000. They both use zx1 chipset:
http://www.mail-archive.com/linux-ker...@vger.kernel.org/msg71934.html

But given the lspci output, that doesn't seem to be the case.

hth,

I just want to confirm that 2.6.34-rc6 booted on my rp3410 (ioz).

 It looks like it reboots
 during USB enumeration or somewhere there:

In order to track this down, I need to know how to reproduce it.
Do you have an USB devices attached? If so, which ones?

I'm wondering if USB is a red herring and something else changed.

Hi Michal,
I strongly suspect it's the same problem we saw on the C3xxx workstations.
Here's the comment in drivers/parisc/sba_iommu.c:

if (!is_pdc_pat()) {
/* Shutdown the USB controller on Astro-based workstations.
** Once we reprogram the IOMMU, the next DMA performed by
** USB will HPMC the box. USB is only enabled if a
** keyboard is present and found.
**
** With serial console, j6k v5.0 firmware says:
**   mem_kbd hpa 0xfee003f8 sba 0x0 pad 0x0 cl_class 0x7
**
** FIXME: Using GFX+USB console at power up but direct
**  linux to serial console is still broken.
**  USB could generate DMA so we must reset USB.
**  The proper sequence would be:
**  o block console output
**  o reset USB device
**  o reprogram serial port
**  o unblock console output
*/
if (PAGE0-mem_kbd.cl_class == CL_KEYBD) {
pdc_io_reset_devices();
}

}


Could you try to make this code unconditional?
(remove !is_pdc_pat() test)

If someone have better ideas on how to handle this...
I can build kernels and test on a J6000.
