kaweth fails to work on 2.6.12-rc[56]

kaweth fails to work on 2.6.12-rc[56]

[Wakko Warner]

Seems that it is unable to send packets however I can see packets coming in.
I downgraded to 2.6.12-rc2 which works.

I have not tested rc3 or rc4 yet.  I am preparing to try rc4.

Just finished testing.
rc2 works
rc3 works (fails on aic7xxx with my scsi hardware but rc5 works with my
	scsi hardware)
rc4 through rc6 do not work.

I am currently running on 2.6.12-rc2

Hi,

have you tried recompiling with debug enabled?
It does show the status codes in the interrupt handler.

Don't forget to report which host controller(s) it fails with,
and which it works with ...

See the last message I sent.  The host controller did not change, only the
kernel version.  The .config really didn't change except for the new stuff
between rc2 and newer.

I have not.  My keyboard and mouse (on a hub) are plugged in beside the
kaweth device so they would be on the same interrupt.

I did notice that the kaweth file itself hasn't changed, but something is
different between rc3 and rc4.

Someone else asked what host controllers.  I tried it on 2 systems.  The
device itself is USB1.  One machine running rc5 used Intel 440bx chipset. 
I'm not sure what controller it has but I was using the onboard USB which
uses uhci.  I don't have that machine anymore, it was temporary.  I'm
currently using this on an Intel E7505 chipset which uses both ehci and uhci
(loaded in that order)

I used the same configfile from rc2 when I compiled rc3 and rc4 (doing make
old config of course).  I'll see about testing this later on.  I don't have
time this morning to look at this.

Sorry, I should be more specific. It will print out the error codes
internal to the USB layer which are meaningful even if interrupts are shared.
Also, are you seeing tx errors in the error count?

Unless I did something wrong, it's apparently not in the USB subsystem.

I have 2.6.12-rc3 and rc4 compiled.  Same config file on a test system.
again, rc3 works, rc4 does not.  I booted rc3 and force loaded the usb
modules from rc4 into rc3.  It tainted the kernel, but it worked.

I booted into rc4.  I do have ACPI compiled so I added acpi=off.  This did
not work, same problem as before.  I left a ping running, the usb controller
was on IRQ 9.  The test system is an old NEC notebook with an Intel chipset
(thus uhci-hcd usb1.1).  I plugged in a Belkin USB2.0 cardbus card (USB1.1
is serviced by ohci-hcd) and plugged the ethernet adapter into that.  Same
problem.

As far as controllers, ALL except 1 (The cardbus USB2.0) has been some
version of Intel.  I have tested this on 4 different systems with the same
results.  An MSI 6163 board, a Supermicro X5DA8 board, a Dell Inspiron 8100,
and the NEC Versa FX.  The Supermicro is running SMP, but I doubt that
matters.

At this time, it's late.  I'll see about reverting files from rc4 back to
rc3 to see which one causes it to work again.

Do you see tx errors?

No.  Oh oops I forgot to say the ping caused the interrupts to increase.
ifconfig showed 1 packet sent but never went up.

This might very well indicate that the queue is not reenabled.
The interrupt handler should do that. If you enable debug in kaweth.c,
you'll learn more. If it doesn't help, I'll send you a patch which produces
more output.
