I've suddenly started getting host not responding messages
on NFS mounts. The mounts are from Solaris8 and HPUX-10.20.
Other Solaris8 machines don't have this problem,
and the machines serving the mounts are unloaded, and responsive.
2.4.7-ac10 worked fine.2.4.8-ac8 through 2.4.9-ac3
have trouble. I have not tested 2.4.8-ac[1..7] yet.

Ok can you transplant drivers/net/tulip from a working -ac into the
current tree and see if that fixes it - that tells us if its a network
driver bug or a kernel core bug.

this is the only diff I find in the tulip directory.
(2.4.8 and 2.4.9 have no diff)

the second hunk could be a problem.

Just a note: This is still a problem.
eventually I'll get a message about task slots.
It's still there through 2.4.9-ac10.
On a new Athlon 1.4 box, with a LNE100TX NIC
it's there with the default kernel from Red Hat Linux 7.1
(2.4.2-2.i686.rpm), and on a P4-1.8GHz with the same NIC.
The servers are Solaris8 and Solaris-2.6, Sparc machines, and the config
hasn't changed in over a year on the 2.6 boxes.
Anorthe system with RHL-6.2 (2.2.14-5 kernel and eepro100 NIC)
has no trouble talking to the servers.
What/how do I set debugging code on the 2.4 kernels to trak
down this problem? It makes NFS mounted home dirs unusable.

Same as mine

Thats the NFS backlog filling. That itself does not indicate a problem of
any kind just congestion - which if the card is getting tx timeouts and
watchdog errors would be reasonable

Well 2.4.2 is in my prehistory pile. I dont know if this has been fixed
or is known - Jeff Garzik may do.
