What version of e100 are you using? we've since enabled MDI-X on most parts with this patch: http://git.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=60ffa478759f39a2eb3be1ed179bc3764804b2c8;hp=09e590e5d5a93f2eaa748a89c623258e6bad1648 Please try the latest kernel or the latest e100 available from e1000.sf.net if that doesn't work we'll need to know what kernel are you using? > lspci reports: > 01:04.0 Ethernet controller: Intel Corp. 82557/8/9 [Ethernet Pro 100] > (rev 10) > 01:04.0 Class 0200: 8086:1229 (rev 10) > > and on another device > 01:05.0 Ethernet controller: Intel Corp. 82559ER (rev 10) > 01:01.0 Class 0200: 8086:1209 (rev 10) > > So it is true that we are revision 10, but 82557/9 not 82551. you're getting confused between decimal and hex. 82551 is rev 16 (0x10) > I must confess that having gotten this far, I am lost.
