I just got the following assertion:
KERNEL: assertion (!timer_pending(&dev->watchdog_timer)) failed at
net/sched/sch_generic.c (631)
which is the outcome of this line in dev_shutdown()
BUG_TRAP(!timer_pending(&dev->watchdog_timer));
when running a sctipt that does
modprobe ib_ipoib
echo 1 > /sys/module/ib_ipoib/parameters/mcast_debug_level
echo 1 > /sys/module/ib_ipoib/parameters/debug_level
ifconfig ib0 192.168.10.118
and then after some time a script that does
ifconfig ib0 down
ifconfig ib1 down
modprobe -r ib_ipoib
below is the dmesg, it might help, the kernel is net-2.6.19 git
Or.
