Subject: tg3: Badness at kernel/mutex.c:207
Date: Sun, 27 Sep 2009 00:20:57 +0300 [thread overview]
Message-ID: <4ABE85B9.3020304@embedded-sol.com> (raw)
Hi,
I'm running linux-2.6.31 on a custom MPC8536 based board with BCM57760 chip.
Both tg3 driver, and Broadcom PHY driver are modules.
Each time I run ifconfig eth2 up, I get the following error message:
Badness at kernel/mutex.c:207

Does it indicate a real problem, or something that can be ignored ?
