-------- Forwarded Message -------- From: Rob <[email protected]> Subject: e1000: TX Unit hangs [PATCH] Date: Tue, 5 Mar 2013 18:55:48 -0500
The e1000 driver in the latest kernel tree still experiences TX unit hangs on some amd64 systems, particularly the SunFire x4500. To work around this, I've made a simple patch based on the latest driver available on sourceforge that adds the ignore_64bit_dma option. Setting this option fixes the tx_unit_hang problem on these machines. I'm sorry I'm not fully familiar with the way kernel development works, and I hope I am sending this to the right person for inclusion. I hope it's ok that it's not a proper git patch - it's tiny and I don't care about attribution.
