[epic] "Too much work at interrupt" with SMC 9432 cards

[Alexander Kotelnikov]

Hello.

I successfully use SMC 9432 cards with linux kernels 2.4 version up to
2.4.2. When I tryed to upgrade to 2.4.4 I got a problem, similar to
one which I have with 2.4.12 (current kernel, 2.4.16 has the same
epic100.c, LK1.1.10)

I have two cards. The problem occurs right after I bring up my
interfaces. Experiments with module options do not help. I got
thousands of lines in log and interfaces do not work at all.

PS Please, Cc: me on replies, scince I am not subscribed to the list.
