Hello,
I'm observing an issue where it appears that tg3 gets wedged into a
bad state every so often, and never recovers. Doing a sequence of
ifconfig eth0 down
rmmod broadcom
rmmod tg3
modprobe broadcom
modprobe tg3
Makes everything work again. The card I have:
03:00.0 Ethernet controller [0200]: Broadcom Corporation NetLink
BCM57788 Gigabit Ethernet PCIe [14e4:1691] (rev 01)
Subsystem: Dell XPS 8300 [1028:04aa]

I'm attaching the log for the full data dump, since my mailer will
wrap it horribly otherwise, but the interesting lines are:
[2234380.228971] tg3 0000:03:00.0: eth0: transmit timed out, resetting

Any further attempts to use the NIC, like ifconfig down/up result in a
similar error log sequence happening. Also, while it's happening, the
computer feels extremely laggy for a short period of time (~1s),
leading me to believe it's doing an uninterruptible sleep of some kind
going on.
This has happened twice, and at least the second time, there was no
unusual traffic on the network. It's linked at 100M, and was probably
doing 10K/s at most when the error happened. If this is insufficient
information, please let me know what I should collect next time this
might happen.
Thanks,
-ilia

Thanks for the report Ilia. I'm guessing the lag is coming from the
driver as it logs the register dump to the syslog.
The register dump shows that interrupts are enabled, but the tag value in
the interrupt mailbox register doesn't match the value in the status block
or the driver's private tag value. I'll see where that leads me.
Stay tuned.

O.K. The interrupt mailbox issue I mentioned above can happen when in
one-shot MSI mode, but it still smells strange. If the tag stored in
the device structure matches the tag value in the status block, there
should be no more work to do. In that case, the driver writes the new
tag to the interrupt mailbox register.
You may be encountering some type of hardware problem. PCIe register
0x104 is the Uncorrectable Error Status register. This register shows
that the "Unsupported Request Error Status" bit is set. This definitely
shouldn't happen.
Do you know if there are any firmware updates available for your system?

I just checked on Dell's website, and I'm pretty sure I have the
latest BIOS. I'll double-check later, but the website says version
A06, as does my dmidecode. So unless they have multiple releases with
the same version number... :) In case it's of interest, the system is
a i7-2600 CPU, 18G of RAM (memtested).
Are there some PCI(e) debug options I should be turning on to perhaps
get a better picture of what's going on?
