The network "works" but very very slow, and ifconfig shows almost the same count in the Tx packet and carrier count: TX packets:23818 errors:0 dropped:0 overruns:0 carrier:23817 dmesg for 2.4.22 and 2.6.5 are almost identical, except for the last lines in 2.4.22 (vortex_up, etc). There are no (apparently important) different in vortex-diag. mii-diag, however, fails to run in 2.6.5 while it works in 2.4.22. Dumps follow, in case someone can shed light. (BTW: lsmod in 2.4.22 shows the module as busy (used twice, because I have two identical NICs, while in 2.6.5 it seems to be unused - I can unload the module with both interfaces up, but obviously as soon as I do that they dissapear - I assume this is the intended 2.6 behaviour). ***** dmesg ***** 2.4.22: PCI: Found IRQ 9 for device 02:0b.0 PCI: Sharing IRQ 9 with 00:1f.4 3c59x: Donald Becker and others. www.scyld.com/network/vortex.html See Documentation/networking/vortex.txt 02:0b.0: 3Com PCI 3c905C Tornado at 0xd800.
