Bug 51689 – tg3 module in kernel 2.6.5 panics (cause may actually be kobject)

• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

[Description Maurice Volaski 2004-05-21 12:39:26 UTC]

The tg3 module in (gentoo-kerne-2.6.5-r1) kernel 2.6.5 panics on boot on a dual-opteron 248 box with 4G RAM. I copied the following screen output...

Reproducible: Always
Steps to Reproduce:
1. use livecd 2004.1 to build a system for dual opteron
2. build kernel with genkernel, include tg3 as driver for onboard ethernet
3. reboot with new system
Actual Results:  
See the details of the crash on boot above

Expected Results:  
not crash :-)

Jeff Garzik says this may be related to kobject and not tg3. He asked if 2.6.6 crashes. Will check as soon 
as I can access an ebuild for it.

I just confirmed this happens in development-sources kernel-2.6.6

[Comment 2 Maurice Volaski 2004-05-31 17:02:28 UTC]

I just confirmed the problem affects kernel-2.6.7-r1 and r2.

Can you open a bug for this at bugzilla.kernel.org as it is a upstream issue, 
not a gentoo specific one.
