There are lots of reports of issues like this for tg3 but most reports end
in "did not hear from requester so closing" or "Fedora Core X is not
supported any more so closing". Does anyone know of a real solution to
this problem. Reading all the bugzilla and Google results for this
problem make my head hurt :-) . Note that the error message
"tg3_stop_block timed out" can be a generic message thus having many
causes.
We have been experiencing intermittent network failures on systems running
SLF47 2.6.9-78.0.1 kernel/tg3 3.86 driver . They waiting for the tcp to
finish, which never happens. The failures are load-related.
This error happened from time to time over the life of these nodes
but they were operating more or less stably under SLF45/x86_64, tg3 3.77
driver.
There are reports of this issue for RHEL 5 too.

--------------------------
The hints we have got thus far is that the new driver v3.86 is
trying to implement one of the tcp offload features on the NIC
which in the case of the BCM5704 is broken.
Any help is appreciated.
