Maybe this issue is RedHat specific but I'm seeing similare symptoms of
my problems listed fairly frequrently these days. The RedHat customers
that I'm talking too are generally just moving back to 5.2 but I
really don't like that answer. Can someone help me shed some light on
My box is a Dell Latitude CPi D300XT.
The PCMCIA net card works fine under RH5.2 and other OS's:

Re: RH6 upgrade and lost network

I posted a similar problem a few weeks ago where it looks
like some kind of
kernal bug. I dropped it while my time was taken elsewhere
but now I'm
forced to confront this issue.
During an FTP operation for example, I keep getting the
eth0: Transmit timed out, Tx_status 00 status 2000 Tx FIFO
My arp tables look fine and the network works fine until this
time-out issue shows up. I am not running any routing
This is running 2.2.5-22. Things were FAR worse under

tools I would

Kernal Hacks Only: Network stops responding when stressed
Fri, 04 Jun 1999 21:27:34 -0700
Network stops responding when stressed under RedHat 6
I am using redhat 6 kernel 2.2.5-15 and -22
If I start to do something network intensive (A CVS "cvs -z3
<EVERYTHING>" operation toward mozilla to be specific), the
If I do an /etc/rc.../network stop; sleep 5;
I can slip some more traffic through for a brief period but
then I need
to restart the network again.
At kernel level -22 I get slightly different symptoms.
I no longer need to restart the network. However my response
become VERY large (35000 ms range; up from 40 ms range). I
these response times for a few minutes and then some resource
appear to be briefly available again (my response times drop
back to the
40 ms range).
This cycle persists until my large operation operation ends.
I can recreate this every time.
I have a gut feeling that this is not a network issue but I'm
ideas to try.
Can someone give me hints as to getting snapshots of what
in use at any given time so that I can start to look for
