Description Ossama Khayat 2004-05-30 17:35:15 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040510

Description of problem:
Starting nfs as 'service nfs start' would freeze the whole system
after almost 3 minutes or less.
I can confirm that i'm using Fedora Core 2 for almost 10 days and
never had this issue at all.
I'm running FC2 on my laptop which is a Toshiba Satellite 2450-S203
with 1GB of RAM/2.8Ghz/nVidia.
I couldn't reproduce the same on another machine (desktop).
I repeated starting the service three times, and it always freezes the
whole system.

Version-Release number of selected component (if applicable):
nfs-utils-1.0.6-22

How reproducible:
Always

Steps to Reproduce:
1. issue 'service nfs start'
2. wait for 3 minutes

Actual Results:  I get an error on rpc/quota of nfs, but still works
as you see in the screenshot. After less than 3 minutes, the whole
system freezes.

Expected Results:  Not Freeze!

Additional info:

This is a clean install on my laptop that I always used since RH9.
Never had this issue before on any linux I used. Also, if I don't
start the service I won't get this problem at all.

Comment 5 Steve Dickson 2004-06-01 14:37:12 EDT
The fact that all of nfs daemons died with "Connection Refused"
tells me its probably a firwall issue... Try service iptables stop
to see if that helps
Comment 6 Ossama Khayat 2004-06-02 17:04:33 EDT
iptables weren't running at all when I used that. Still the problem
exists. Is there any more output/diagnostics I need to provide?
Comment 7 Steve Dickson 2004-06-03 06:30:22 EDT
Can you turn on the AltSysReq keys (by echo 1 > /proc/sys/kernel/sysrq)
then typing Alt-SysReq-P to see what the processor is doing?
Comment 8 Ossama Khayat 2004-06-05 17:12:05 EDT
As soon as I press SysReq key (with Alt ofcourse) I get a screenshot
of my desktop.
Sorry, don't know how/if this can be disabled.

Red Hate -> Preferences -> Keyboard shortcuts.

Then delete the option for "Take a screen shot of a window".

Comment 10 Steve Dickson 2004-10-14 17:27:10 EDT
Does this still happen with more recent FC2 or FC3 kernels?
Comment 11 Dave Jones 2005-04-16 01:21:27 EDT
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat.  The Fedora legacy project will be producing further kernel
updates for security problems only.

If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.

Thank you.
