Hi all!
I get the same bug again and again, always when ifplugd is started:
tg3: eth0: No firmware running.

With 2.6.19-rc2 (no -mm) it does not happen.

BOTLEY
The prominent stain on a man's trouser crotch seen on his return from
the lavatory. A botley proper is caused by an accident with the push
taps, and should not be confused with any stain caused by insufficient
waggling of the willy.

There are tg3 changes in -mm, but I doubt it they caused this hang.
Can you test 2.6.19-rc2 plus the below?
Thanks.

FWIW, I have a tg3 running just fine with 2.6.19-rc2-mm2, on x86-64.

It's OOPS'ing by softlockup'ing in udelay() and then we get a corrupt
backtrace.

2.6.19-rc2 works
2.6.19-rc2+patch does not work
So it is this patch.
hw:
Acer TravelMate 3012WMi

If you need dmesg, .config, something else, no problem.

It doesn't make any sense. This patch is totally benign and
cannot cause the "No firmware running" and lockup that you
reported. Can you please double-check?

The unwinder-based backtrace is screwed up (yet again) but the old-style
backtrace is there, in all its messy glory.
Weeding out the crap, I think it's this:
[<c01d03af>] delay_tsc+0xb/0x13
[<c01d03e0>] __delay+0x6/0x7
[<c022c240>] _tw32_flush+0x3f/0x51

It's strange that the post-2.6.19-rc2 changes triggered this - that code
won't have run yet.
Norbert, are you really sure?

Ok, I cannot reproduce it anymore. No idea why it happened.
ANyway, with my current rc2+tg3 patch I have no problems, while with
rc2-mm2 I have the problems.

And again I can reporduce it. How, (again, please don't lough):
I booted into windows (sometimes one has too, contract from the EC with
macros in Excel tables ... grrr).
WinXP didn't mange to get an IP address from my cable modem.
Rebooting into linux, same problem as reported,
and, but no idea whether this is related: the modem just looses sync and
need several resets until it find back into syncronization.
I will do some more experiments with Win-different linux kernel
switching.
Sorry for the chaos, no idea what has happened here!!!
Best wishes
