I saw these in kernel log:
eth0: Too much work in interrupt, status e481.
eth0: Too much work in interrupt, status e081.
After these, the interface is still up but nothing goes through it, ie. it
looks like a black hole.
ifdown eth0 ; ifup eth0 fixes that.
max_interrupt_work can probably be tuned, but that's not the real problem.
should wake up back after having too much work when there is no longer so
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases,
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
