NCR_700 problems on 715/64 with 2.6.11-rc4-pa1

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.

Hi Michael,

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 ;-)

I got lot of messages as follow:
