tg3 kernel bug in 2.6.18-mm3 and 2.6.19-rc2-mm2

[Norbert Preining <preining@logic.at>]

Hi all!

I get the same bug again and again, always when ifplugd is started:

 =======================

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

Normal dmesg gives:
tg3.c:v3.66 (September 23, 2006)
PCI: Enabling device 0000:03:00.0 (0000 -> 0002)
ACPI: PCI Interrupt 0000:03:00.0[A] -> GSI 17 (level, low) -> IRQ 18

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.
