      How often does this occur?  A lot, or just once or twice?

i'm seeing this, too. it occurs *very* often during access of the card:

Apr 13 11:08:11 kleineronkel kernel: eth0: Too much work at
interrupt, IntrStatus=0x0001.

Apr 13 11:18:09 kleineronkel kernel: eth0: Too much work at

interrupt, IntrStatus=0x0001.

and so on.

it might be important that i'm sharing the IRQ:

and yes, this is an SMP box (dual p3/600) with a bx chipset.

please keep me on cc:, as i have only archive access to LKML. thanks.
btw, jeff, the old "kernel: eth0: Abnormal interrupt, status 0000000[2,6]" messages have disappeared since 2.4.3 or so.

regards,

I've fixed this locally. I just need to test all the RTL chips (five or six variants) before I send the next patch to Linus/Alan...

In reply to Jörn Nettingsmeier

hello jeff !

with the 8139too v. 0.9.16 from
http://sourceforge.net/projects/gkernel/ and kernel 2.4.4-pre3, i see no more errors of the "too much work at interrupt" type.

i used to see the errors even under normal load, starting immediately after booting.
so far, i did some nfs and flood-pinging, and all seems to be well.

if you want me to run more specific tests, let me know.

thanks,

jörn
