(NET E100) Fedora Core 2 Freeze on Wakeonlan packets hit the network card
Last modified: 2015-01-04 17:05:53 EST
Description of problem:
After installing and a fews hours on the HP Vectra computer, the
Linux freeze. It still answer to ping, but all services (even
console) doesn't reply. I had that problem using test3(which did
output information when frozen) but someone from #fedora told he the
final would work fine. But it dont, sorry I havent submit a bug
Let me know if I can do anything to give you more information.
Version-Release number of selected component (if applicable):
Fedora Core 2 final (Test 3 also)
Install Fedora Core 2 on a HP Vectra. and wait
Steps to Reproduce:
1. Install Fedora core 2 (I use minimal install)
Should continue to work
I just tryed again on a Compaq EVO D510 (P4 1.5) and same probleme.
I wonder if it might be the traffic on our local network that just
make the kernel hang. I'll reboot the machine and let it unplug from
the network and see.
Wakeonlan make the kernel FREEZE.... NOT GOOD
What network chips are these two machines using ?
thet both use the e100 driver
I tryed it again on my Evo (by tcpdump > to the HD) and once the pc
crash, it wont boot again anymore, Bios dont detect the Harddrive.
Not good, Going to try another harddrive soon and see if it just HD
or machine are is dead
HD Dead, Maxtor DiamondMax Plus 8 20gig ATA/133HD. Viva warrenty.
This problem really cause alot of bad thing. Hope you can fix it.

the WOL request machine send about 4900 of these packets (600 time to
7 different VLAN)
After that, the linux is crashed
Those are UDP broadcasts not wake on lan packets as far as I can see.
As to the disk, Linux has no way of breaking the disk - thats just
well those are the packets another linux machine capture from the
network card. As for linux breaking the HD.. May be it just bad
luck, but it not old machine and on 550 PC, it would be the first
that does that over here. I'l attach a dump file that work from the
HP machine (up until it crashed)
Created attachment 100424 [details]
tcpdump -i eth0 -vv -n > dump.info
From the HP Vectra PC FC2 (Minimal install)
Created attachment 100425 [details]
tcpdump -i eth0 -vv -n > dump2.info (test 2)
From the HP Vectra PC FC2 (Minimal install) (Another test)
I did a manual wake-on-lan on the Linux MAC and it crash. I tryed
other MAC and it was fine.
Is there any update on this ? I can't put that box live if it
vulnerable to DoS attack
At the moment I can't duplicate it on any e100 hardware I have nor can
find any reference to the same problem anywhere else on the internet.
That makes it kind of hard to fix.
Ok here my new testing :
rmmod e100 after system is booted, and doing wakeonlan again, and
system still crash
But I just thought to REMOVE ACPI and APM (linux acpi=off apm=off at
boot time) and it fine, doesn't crash anymore.
Want the wakeonlan program I use, I open source, but I lost the
I think this sound a bit like the 129103 bug lots of folks seem to be
ancountering on stock core 2 2.6.5-1.358
hangs our ibm e server pentium 4 . No console or login services work
from then on but we can ping the box.
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.
