[1.] ne2k-pci freezes with APIC error on 2.4.0-testX SMP

[2.] bug. (as i don't think it is a feature :)
found in all 2.4.0 versions i tried: test5, 6, 7, 8, 9, 10, 11

When doing massive NFS transfers (2.4 machine as the client) on my SMP
box
(Abit BP6 2x celeronA 533mhz (non-overclocked) 64Mb ram, latest
apt-get-ed
debian woody) my ne2k-pci card (Realtek Semiconductor Co., Ltd.
RTL-8029(AS)
 (rev 0)) suddenly stops working. test5 spits that in syslog:

Aug  4 23:08:51 sonic kernel: Linux version 2.4.0-test5 (root@sonic)

in test 6,7 and 8 it dies silently (no syslog messages)

also in test11 is quiet

in test9 and 10 dmesg will show:
kernel: APIC error on CPU1: 00(02)
kernel: APIC error on CPU1: 02(08)

the errors usually apear in pair and on CPU1 but sometimes also on CPU0.
if
it'll helps i'll send you `grep "APIC error" syslog`

those errors will apear immediatelly before the net card hangs but also
at
random times with no effect on the network card (ex: when the sound card
plays soething it spits the APIC errs and immediately after a Sound: DMA
(output) timed out )

The card acts like the UTP cable is cut (but the hub led is still on).
ifconfig down/up does not help. rmmod insmod neither. Neither resetting
the
hub or trying to connect the card trough BNC and back to trigger media
autosense. Only reboot helps.

[3.] kernel 2.4 network smp ne2k-pci apic

[4.] 2.4.0test5 trough test11 - kernel from ftp.kernel.org

[5.] no oops

[6.] This fennomenon is usually triggered by large nfs transfers
(watching a
divx from a directory mounted from another machine - after 100-300Mb it
dies) but sometimes even by simple telnet/http/ftp sessions.

The bug is not reproductible with small transfers - sometimes it will
die,
sometimes not. It will certainly lockup after transfering fast (cat,dd)
some
1G file over nfs of ftp-ing that file.

after a freeze the interrupt count in /proc/interrupts for the network
card
does no longer increase 

the other machine used for the test runs 2.2.13, has a Xircom cem33
pcmcia
net card, latest Debian woody, tried with kernel-nfs-server and
user-nfs-server.

2.2.x SMP/nonSMP works O.K. 

2.4.x SMP booted with "nosmp" or "numcpus=1" will act funny (at least
the
versions 5 trough 8 ) - the network card remains on IRQ17 but the
machine
with only one cpu is not able see beyond IRQ15 .

the Realtek card never gave a glitch before.

i'l be happy to run any dang test you'll want me to run.

PLEASE help me. This bug is REALLY annoying. I don't want to switch back
to
2.2 as 2.4 is WAY faster and i certainly don't want to remove one cpu :)

if you have some questions or answers - reply to this e-mail address as
i am 
not subscribed to linux-kernel

Thank you very much... (and congrats to Linux for the new daughter :)
