[parisc-linux] NCR_700 problems on 715/64 with 2.6.11-rc4-pa1

[Helge Deller]

I get random messages from the 53c700 scsi driver (see below). 
Any ideas ?

Looks like more udev/irq balance/irq routing problems,
see concurrent thread "BUG 2.6.11-rc4..."

try: 'noudev pci=routeirq' options on the command line
to change behavior in generic code.

I will try, but I'm not sure that this is the cause.
Looks to me more like a missing ioremap() call.

Even the sti framebuffer does not work since weeks - I think it's due to ioremap() as well.

With 2.6.11 the device drivers are responsible for registering
their irq handling, not the bus driver...
Could that also be the cause for your missing ioremap() calls?

The above is a general description - perhaps not exact.
I am afraid I will learn more than I ever wanted to know about
this change before I get this *&%^&  tulip driver working under 2.6.11

Yup.  This is a missing ioremap() in the 53c700 driver.  I'll have a
quick look, see if it's easily fixable (should be).  If the dmesg noise
annoys you, you can just turn off CONFIG_DEBUG_IOREMAP, but thanks for
reporting it -- it's an important step towards turning on HPPA_IOREMAP ...

Hi all,

Here isthe lot of messages I got when stressing sdc on narrow se connection of my c110 (this disk is an older model then mentioned 
in previous test).
using following stress test just being:
# tar cslp linux-2.6.11-rc4-pa1-050219 | tar -C /chroot/Develop -xslp
# tar -cslpf /chroot/Develop/linux-2.6.11-rc4-pa1-050219.tar linux-2.6.11-rc4-pa1-050219
# tar -cslpf /chroot/Develop/linux-2.6.11-rc4-pa1-050219.tar2  linux-2.6.11-rc4-pa1-050219
nearly simultanious in 3 different shells ;-)

That said it seems to be a c110 pb because as reported in 
<http://lists.parisc-linux.org/pipermail/parisc-linux/2005-February/025853.html>

The same test on b180 with same 53c710 driver doesn't encounter any pb :-)

I can so eliminate disk pb ;-)
But how may I check if it's hw pb in the 53c710 ctrlr? (hp ode expert tools are only for hp engineer)

hth,
