Interrupt handler not syncing

Reproducible: Sometimes
Steps to Reproduce:
1.reboot - pump running - masq enabled - brought up ipchains manually 
after network started due to script issue needing ip addy.
2.login - wife's account
3.ping my.work.machine.gov - aiee.... panic!!!

happened at least twice. I had one other crash this week (installed RH 7.1 
on tuesday - today friday)- however didn't check it out.
	

Actual Results:  System crashed with above output. First time just powered 
off/on force check ok. Second time power off/on had to run fsck / 
manually. Last time power off/on force check ok. SInce then did 
interactive setup and did not bring up ipchains or eth0.

Should be noted that I had just compiled perl 5.6.1 and tried to install 
Bundle::LWP with perl -mCPAN -e shell ... some install errors on module 
Net:FTP

Also had just ran tripwire. Then I crashed for the night. Tried to telnet 
home from work the next day and couldn't called wife. She logged in and 
tried to ping my machine and this produced the error. Same error 

Expected Results:  Dunno .... came here instead! Enabled dhcp and ipchains 
on old 486dx 33 with Debian potato (2.2) never dies! but not a 10/100 
card. Thus wanting to look at redhat .... hummmmm

Kernel panic: Aiee, killing interrupt handler!
In interrupt handler

This computer is a old HP PII233 with 2 new Linksys 10/100 LNE100TX cards, 
a new generic 40 X cdrom, a 30 GB WD 5400 new harddrive and an old floppy.

Comment 1 Brock Murch 2001-04-28 03:54:16 UTC

Just happened again... I brought up pan and was attempting to go to news-
reader. eth1 died (I had disabled eth0). I tried to bring up eth1 and the 
system locked up.

Comment 2 Arjan van de Ven 2001-04-28 08:51:08 UTC

Can you give the output of "lspci" so we know exactly what networkcard it is?

Comment 3 Brock Murch 2001-05-01 21:14:32 UTC

I can't do it from redhat but.... with mandrake it is:
They are linksys Model LNE100TX Version 4 (I have two of them) The drivers
wouldn't compile under 2.4 and RD 7.0 has corrupted libs as you know, so I was
outta luck and installed mandrake 7.2, compiled the drivers and everything works
great!

Comment 4 Brock Murch 2001-05-01 21:18:11 UTC

Oh ya, I forgot to mention that this happened all the time (very reproducable).
And I did notice that eth0 or eth1 always went down just prior to the crash.
ifconfig showed one or the other down by itself just prior to crash..... good
luck!
