Description Chris Chabot 2001-02-14 05:52:06 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.4.1-ac11 i686)

when using the bonding driver supplied in the 2.4 kernel (bonding.o) to
bond 2 network cards, redhat (ie kernel) crashes on system shutdown (when
unloading the driver)

Tried this on both rh 7.1 supplied kernel (normal,smp,enterprise) and on a
self compiled vanilla 2.4.1 kernel, they have the same bug

Tested on a SMP dual p3 600, with 2x 3c905B network cards.
/etc/modules.conf contains alias bond0 bonding
ifcfg-eth0 & eth1 are configured for master=bond0 slave=yes

bonding driver loads perfectly, and functions perfectly, but crashes on
system poweroff/shutdown. This is causing me a lot of fsck's since it cant
shut down normaly

Reproducible: Always
Steps to Reproduce:
1. setup a bond0 device
2. ifdown bond0
3. ifdown eth0 (or 1)
*crash and burn*

Also reproducable by doing 'poweroff' or 'shutdown'

Expected Results:  bring down interface.

Alan, has this been fixed in any of your -ac releases?

Comment 2 Glen Foster 2001-02-15 23:09:01 UTC
We (Red Hat) should really try to resolve this before next release.

Comment 3 Michael K. Johnson 2001-03-01 04:55:24 UTC
This is fixed in our latest rawhide kernel.
