For standard frames, 82573/82574/82583 can enable L1 but L0s must be disabled, and for jumbo frames 82573/82574 must disable L1. This allows for some parts to enable L1 in certain configurations leading to better power savings. Also according to the same errata, Early Receive (ERT) should be disabled on 82573 when using jumbo frames.

I built an OpenSUSE 11.3 kernel with just this patch reverted and the problem no longer occurs.
Just to confirm this happens in the upstream 2.6.36-rc3, right? 19833b5dffe2f2e92a1b377f9aae9d5f32239512 upstream does not fix it? If it still happens upstream please report it to LKML and CC the Intel folks. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Right, but did you try it in the upstream Kernel (e.g. 2.6.36-rc3)? If it is still happening in the upstream Kernel then can you report it upstream? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
