Description of problem:
When netdump is set up, and then the network cables are removed, the system
hangs after a crashes
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Setup netdump
2. Remove network cables
3. Crash system (sysctl -w kernel.sysrq=1;echo c > /proc/sysrq-trigger)
The terminal window assocaited with this command seems to scroll for a while,
then hang. If the network cables are re-inserted later, the system is still hung.
Either do the dump after the cables are re-inserted or just reboot.
Customer found out that is netconsole was not running that this bug didn't show.
Seems to indicate a problem there. Seach showed that fix for bugzilla 127815
(from RH3) did not make it into RH4. Created bugzilla 191342 to track that.
