2.6.19.2 sky2/acpi crashes

2.6.19.2 sky2/acpi crashes

[Lionel Landwerlin]

Hi,

I'm running a macbook with a Marvell ethernet controller, and I have a
lots of freezes when using the ethernet controller under a load of
~100K/s. Since I'm running a 2.6.19.2 kernel, I'm able to get some
report from the kernel. Here they are :

As most of the time, the keyboard gets locked and the network driver is
down, I can get more informations.

Ok, that's done. Same problem.

Just to show you I did not forget to remove processor.ko from initrd
image, I tried to load speedstep_centrino :

idle=poll seems to fix the problem (cpu fan is running almost at full

It sounds like issues relative to Processor C state.
Please enter a bug in ACPI category on bugzilla.kernel.org

Actually, the test above with the processor module removed proved
that it isn't ACPI C-states -- as they will not be available.
You should be able to observe that /proc/acpi/processor/*/power
does not indicate any C-state use when processor is unloaded.

My guess was that some deep C-state with long exit latency
was interfering with the device.  booting w/o the processor
module should have left you running the native mwait idle.
booting with idle=halt should have left you running the HLT idle.
booting with idle=poll is a busy spin loop that never enters
any hardware power saving state.

I'm quite puzzled that idle=halt was not sufficient to solve the issue,
because that should be the lowest exit latency idle loop.
So maybe I'm wrong about the cause -- though I can't then
explain why idle=poll helps...

All of the idle selection options cause the kernel to print
a line with the word "idle" in it.  Perhaps you could search
your dmesg for "idle" to verify that it is running what we
think it is?

Here I join the complete log for idle=halt

I'm running idle=poll for more 1 hour now with heavy ethernet load, no
crash. It usualy happens in 10~15mn with idle=halt and 4~5mn with no
idle option.

it is indeed doing what you asked it to
Jan 24 01:11:21 cocoduo kernel: [   30.741018] using halt in idle threads.

I think my guess is wrong.  If idle=halt doesn't help, then the failure
doesn't have anything to do with the idle loop and power saving idle states.

I can't explain why idle=poll helps.

I am also having trouble with the sky2 module, though I've not yet seen a
oops, the driver stopped working after some heavy traffic (copying some G
of data). Only rmmod sky2; modprobe sky2 resolved this. (I am also on
2.6.19.2 but I've seen this happen on 2.6.20-rcX too).

Ive also had the same problem with both 2.6.19.2 and 2.6.20-rcX,
motherboard is gigabyte ga-965-ds3 , the networking stops completely
under moderate traffic, I get the following errors or a complete
lockup:

Jan 21 02:08:04 beast NETDEV WATCHDOG: eth0: transmit timed out
Jan 21 02:08:04 beast sky2 eth0: tx timeout
Jan 21 02:08:04 beast sky2 eth0: transmit ring 475 .. 452 report=475 done=475
Jan 21 02:08:04 beast sky2 hardware hung? flushing

At the time I was downloading a iso image at 850k/sec, so not really a
high network load at all.

rmmod / modprobe does resolve the issue, but more times than not the
box locks up completely instead of getting those errors.

I am on a completely different system (macbook pro 1,1) with PREEMPT and

I get problem reports all the time, unfortunately, so far these have
not been reproducible on the configurations and hardware I have. I am
not denying there is a problem, but if I can't reproduce it, it takes
a long time to fix.

Your problem seems to be missed/lost interrupts. If you display
the contents of /proc/interrupts (ie cat /proc/interrupts), it
will show whether level (good), edge (bad) or MSI (good if hw works)
are being used.

Some workaround related things to try are:

1) Adding the module parameter "idle_timeout=10" will cause
the driver to poll for status every 10ms. This is obviously a performance
overhead but it can allow system to function.

2) Disabling MSI with either "pci=nomsi" on boot cmdline or by using
module parameter "disable_msi=1".  Message Signaled Interrupts are good,
but it seems some chipsets don't work right.
