It boots up fine and everything, but the Gbit network adapter does not work. It runs into watchdog timeouts and/or produces internet storms on the rx and tx interrupts. Since the driver itself hasn't changed since 9.1 (which is the last working version I have), I suspect that something else (DMA?) was changed in the meantime. I prodded aroudn what's happening in the driver. Any pointers as to where to look for the problem? I prodded around what happens in the driver and it seems that DMA doesn't work properly (descript= ors are set up etc, tx interrupt happens, but the descritor is still owned by t= he DMA).=20 Cheers, Markus --jq0ap7NbKX2Kqbes Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (DragonFly) iQIcBAEBAgAGBQJSvyAbAAoJEBRHBRYBD4mP1MEP/10JZr1bsoSEb9lRjaNJa9Iy xj5HwdHFDv2kBGgF29+R8NSn9IRSRiQb7aaM0BnBpOKx4/4mutjI718AK1a7goKD K08WbOIVUYK0fciyPqiMR4HFdD0U/wlySTcuLSCVdfsWjmkFWFQ/99kPJVZa5ZJe SWlcXENIR4jtwF0tWFkve9NBxi47J8DMyal0KLv+piHufzNwB4l0VxzknFVv5AWr DQiWNXTXd7qsuvLdjOIXIcgL7b0WTaVRoMldy6bLDkd5AnKsqZKMzaiZBXntgTji WMG6NguDnFZBCB1AN8/XO0D97eI5PB6I6TprteCOxFMjM0Sy+K5nSCqdi56uzsFn zl4ksmFrkrLRoED9kvhIvAOHk1YiG7/lL3s49qe51/OtUHT1HfxtEKPILagaziQC G9xrYf0bfJ5KKZwJtBXod5h0P+AUhcCtHHASWCNSFDUxuKmBPvxCjeJcsiteZqtc fDurQh+IxPsPStb3wVsUOI+NSw+sgEMs528Ox7QyMnkPQ7jGdQTJDIfcnN9pZ+WZ vKeTcu9NqI34FV7nyGXavJGVUHMno/gZh9tMMBzbX5LYmPn1XKF1J8hlVCMxzNZN gbYqWp1sQ1G1yK0YaqAh2Jeqp1GPO93PiRa/D+VMagNAytBjiQKRDgwxr/nWz/UA mWlglPOcG7qrlQl0fJeB =xM/H -----END PGP SIGNATURE----- --jq0ap7NbKX2Kqbes--
