When trying to launch netcfg from gnome, the entire system hangs (freezes,
locks up, non responsive, no keyboard or mouse possible).
Steps to Reproduce:
1.Start X (using gnome, haven't tried anything else)
3.completely hung at this point
Actual Results: hard system hang
Expected Results: netcfg should have launched
I'm testing on a Dell 2400, with Dual 866 SMP configuration. The adapters
installed are AMI Megaraid (perc2/dc),IBM PCI token ring adapter
(olympic), 3com 3c905c-tx, adaptec a7xxx (for tape and cd). The system is
configured with 512mb memory. The problem is easily reproduceable.
We (Red Hat) should really try to resolve this before next release.
What kind of video card do you have? Can you access the affected system over
the network? I can't reproduce this on my test system.
My video is an ATI Rage 3d (mach 64 driver). I'm suspecting 2.4 kernel
problems either with PCI or Token-Ring on the Dell servers. The Dell 2400's
have 2 seperate busses, and when I try to insmod the olympic driver by itself,
I get an error indicating (I don't have the exact text handy) that it's having
problems with the PCI interrupt.
Does this only happen when a particular driver is loaded (i.e., the
aforementioned olympic driver)? Does it continue if you update to the XFree86
and kernel packages from Raw Hide (ftp://ftp.redhat.com/pub/rawhide/)?
That seems to have helped netcfg. It no longer hangs with the new kernel and
xfree86. I'm suspecting the kernel updates. I'm still getting kernel panics
though, but not as frequently. I'll track that under my other bug report
though. You can close this one out as fixed with the new kernel and xfree86
Will do. Thanks!
