RaQ2+ NIC problem
hello,
i currently have a big problem and i hope someone could help.
I am running debian woody with kernel 2.4.18 (fresh from the current
cvs tree)on a cobalt RaQ2+. Everything works smooth but one or two
times a day all network traffic stops. The server is still running
and i can log into the RaQ2+ on the serial console. If i restart the
network (/etc/init.d/netwroking restart) i get no errors and
everything works well again.
The tulip driver is 0.9.15-pre9. So i decided to upgrade to kernel
2.4.20 because the driver there is 0.9.15-pre12. It took some time
to get a stabel configuration. Now with the kernel 2.4.20 the
network problem is bigger than ever. Simply loging into the RaQ
with ssh and running midnight commander is freezing the nics.
Or if i log into webmin the nics freeze as soon as the first
website appears.
The same effect is with kernel 2.4.21. Therefore i recompiled
all kernels with tulip support as module to get greater flexibility
(it´s much easyer to play with insmod and rmmod). No matter
what otpions i use (10Mbit, 100Mbit, Half or Fulldublex) the
results are still the same:
- kernel 2.4.18 with tulip 0.9.15-pre9: nics freeze 1 to 2 times a day
- kernel > 2.4.18 with tulip 0.9.15-pre12: nics freeze after just a few
minutes
I played with the tulip drivers and compiled later revisions as
modules to use with kernel 2.4.18 and earlyer revisions to use
with kernel 2.4.20 and above. No effort.
Fortunately i have six RaQ2+ so i can test different kernels with
different tulip drivers but this is driving me nuts. I spent
nearly 4 hours each day for the past 4 weeks to get rid of
this nic problem but i dont know what to do next.
Btw. even if i use only one nic (no matter wether eth0 or eth1)
the problem occurs. I have an old RaQ2 with only 1 nic running
stable on 2.4.18 with tulip 0.9.15-pre9.
Unfortunately tulip debug mode is not working (neither in the kernel
nor as an option while loading the module) so i cant see any
problems within the nic driver. I tried to compile tulip-diag but
this is not working due to limitations of the kernel source tree.
>From other lists i know there are many people having this problem
but none of them has ever solved it. Any ideas what i could do
next or do you have a solution?
Your feedback is welcome.
Best regards
Michael
