Description David P. Reed 2007-02-26 11:03:11 UTC

Most recent kernel where this bug did *NOT* occur: 2.6.20
Distribution: fedora core 6, new kernel
Hardware Environment: HP dv9000z laptop (AMD 64x2 SMP, nforce chipset, 2 GB ram)
Software Environment: kernel 2.6.21-rc1 built using FC6 .config options.

Problem Description:
after boot, eth0 stops working

Steps to reproduce:
build kernel, install, boot.   driver loads, but after about 7 packets, stops
working - no packets getting through.

back out just the forcedeth.c diffs, kernel works as well as 2.6.20 (better,
actually, since sata_nv seems to be less buggy), in particular eth0 works.
