Hi
Ultra 10 can boot, it receives DHCP answer, ssh works, but few minutes
after machine becomes unresponsible by net at all.
It does not respond even on ARP requests.
On Sparc host I see that `TX packets` does not grow, but RX grows.
The state of the interface is
UP BROADCAST RUNNING MULTICAST
There is no relevant kernel messages in dmesg.
next-20090317 worked fine.
Let me know if I can help.

I have reproduced it on next-20090318 for the second time, but still
do not know how.
next-20090317 might be affected.
Now both packet counters grow, but tcpdump cannot capture any packet.

Does the current vanilla kernel work fine?

Yes. The problem happens only with -next tree.

I have one of my ultra10s up and will try to reproduce and diagnose
this locally.
Thanks.

Hi David
2.6.29 also does not work.
The guilty patch should be between 2.6.29-rc8 and final 2.6.29
even more narrow - 59fcbdd..v2.6.29
I can try to bisect.

No, it is wrong, sorry.
I will do more tests tomorrow.

I bet it is the problem we are discussing here:
http://marc.info/?l=linux-kernel&m=123789980524715&w=2
Herbert has posted two patches to try and fix this issue,
you can try the second one to see if it solves your bug
too.
