Please notice that the card is called 905-CX (notice the X after C). This
is a new "generation" that had this problem, undocumented by 3Com until
now (they exist for about a year now). The driver in 2.2.19 and around
2.4.3 has a fix (Don might say "workaround") which works 100% (or let's
say that after this was introduced no more complaints came). There was
also a problem with (mis)identifying the MII, but this was also solved.
However, CX cards seem not to be very wide-spread. Most people can get
905-C (notice that there's no X after C) - these cards also work very
well.

Side note: "naming conventions" from 3Com are something like:

C or CX	- type of the card
TX	- 100BaseT
M or NM	- managed or not (a.k.a. includes boot ROM).

Side note 2: it might be the third time that I'm posting the info about
C-CX differences. Aren't today people able to use search engines ?

Sincerely,

Bogdan Costescu
