Re: aic7xxx and 2.4.3 failures

[Gérard Roudier]

Looks like an IRQ problem to me.
I mean the kernel wants to change IRQ routing and just do the wrong job.

Ingo reported me a similar problem a couple of week ago that made failed
the sym53c8xx driver. Looks very similar to this one with the kernel PCI
code wanting to assign IRQ 11 to almost everything.

Btw, I donnot know the cause of the problem since I am still expecting
some reply following some suggestions from me. :-)

aic7xxx and 2.4.3 failures

[Jim Studt]

I've got a trio of identical PIII machines all failing with aic7xxx under
2.4.3.  I've tried both aic7xxx 6.1.9 and 6.1.10 in addition to the one
in 2.4.3 (6.1.5?).  These machines work fine under 2.2.18pre21.

I'm looking for any ideas or suggestions on how to fix this.
(Ok, honestly I'm hoping someone will say `you fool, read this message',
but I don't have high hopes for that.)

A typical startup with 6.1.9 proceeds like this...  (6.1.10 hangs silently
after emitting the scsi0 and scsi1 adapter summaries, maybe it is
going through the same gyrations silently.)

Try saying N to the AIC7xxx driver and Y to AIC7XXX_OLD and see if that works.
This is important both because it might solve your problem for now but also
because if the old driver works we can be fairly sure the bug is in the 
new adaptec driver and not elsewhere and triggered on it

Using AIC7XXX_OLD does not work either.  Different output....

Re: aic7xxx and 2.4.3 failures

[lists]

I confirm similar problems (see my message from yesterday).
AIC7XXX_OLD also failed for me. I have tried aic 6.1.8 as well
as 6.1.10. 

Both 2.4.0 under redhat 7.0 and 2.4.1 as shipped by redhat 
wolverine work. As have all earlier versions going back to 2.3.xx
and 2.2.x

Re: aic7xxx and 2.4.3 failures

[Jure Pecar]

I can add a "me too" to this thread.

I began playing with 2.4 releases (again) at 2.4.2-ac23 and i can't
manage to boot it properly, even the 2.4.3-ac2. I have an adaptec 2940U
(aic7860 as driver tells me) and both drivers, old and new, dont work
properly. Either i get request_module[scsi_hostadapter]: Root fs not
mounted, and then what seems to be a random oops a couple of seconds
later in the beginning of the init scripts, or, root fs doesnt get
remounted rw, which is followed soon by some oopsen. I reported one back
then (
http://boudicca.tux.org/hypermail/linux-kernel/2001week13/0077.html ).

Looks weird ... have there been any changes around aic driver recently?
I can try to write down some more oopsen if anyone is interested ... 

On the other side, 2.2.19 with new aic driver 6.1.10 is working just
nice ...

I had similar problems w. 2.4.3 on an SMP aic7xx PII, box: new driver
never managed to mount the root partition - always panicked first. Old
driver worked fine.

I am using 2.4.3-ac3 successfully with 6.1.8, 9 and 10, and now building
with 11.

Re: aic7xxx and 2.4.3 failures

[Igor Mozetic]

For me 2.4.3 + aic7xxx-6.1.10 work fine. I just changed the default
bus settle delay from 15000ms to 5000m, and enabled APIC:
CONFIG_X86_GOOD_APIC=y
CONFIG_X86_IO_APIC=y
CONFIG_X86_LOCAL_APIC=y

The machine boots, devices are properly detected (unlike 6.1.8),
CDRW reads and burns fine, CDROM works (IDE-SCSI).

Intel C440GX+ UP, Adaptec AIC-7896/7, 2GB RAM, CDRW Sony CDU948 4x/8x
