Sure Komuro, there they are in kernel log:
Sep 17 23:51:37 (none) kernel: eth0: 3Com 3c562, io 0x300, irq 9, hw_addr 00:60:97:FF:B7:08
Sep 17 23:51:37 (none) kernel: 8K FIFO split 5:3 Rx:Tx, auto xcvr
Sep 17 23:51:37 (none) kernel: ttyS03 at port 0x02e8 (irq = 9) is a 16550A
Sep 18 00:02:31 (none) kernel: eth0: switched to 10baseT port
Sep 18 00:03:10 (none) kernel: eth0: interrupt(s) dropped!
Sep 18 00:04:07 (none) last message repeated 3 times
Sep 18 00:05:10 (none) last message repeated 6 times
Sep 18 00:05:58 (none) last message repeated 6 times
"message repeated" appeares after shuffling some files to and fro.
Also seems like there is a throughput drop roughly at half maybe.
Well, and /proc/interrupts before:
CPU0
0: 1076973 XT-PIC timer
1: 14348 XT-PIC keyboard
2: 0 XT-PIC cascade
4: 322858 XT-PIC serial
5: 1 XT-PIC soundblaster
9: 0 XT-PIC 3c589_cs
12: 135774 XT-PIC PS/2 Mouse
14: 7778 XT-PIC ide0
NMI: 0
ERR: 1
and after some network traffic:
CPU0
0: 1178150 XT-PIC timer
1: 15090 XT-PIC keyboard
2: 0 XT-PIC cascade
5: 1 XT-PIC soundblaster
9: 0 XT-PIC 3c589_cs
12: 143255 XT-PIC PS/2 Mouse
14: 8178 XT-PIC ide0
NMI: 0
ERR: 1
same after card ins/rem, no increment in irq 9 count whatsoever.
detected ok though, as i said before, due to poll_interval.
So, not all is a charm as i thought at first.
Supplying i82365 with other parms and without the poll_interval makes no good also.
