ex0: interrupting at irq 5

(nothing else on irq 5)

machine which is fairly heavily used in terms of network, we fairly frequently see:

Jan  5 10:04:25 mirror /netbsd: ex0: uplistptr was 0

It pauses the machine for a while before carrying on. That on its own would be 
ok, but so far, roughly every 12 days, the nic stops responding completely. We 
have a serial console attached and could login that way, but no amount of 
ifconfig massaging (up, down etc) made ex0 come back. Reboot was neccessary.

There was a mention on mailings lists about increasing a:

#define EX_NUPD         128

Will that solve the occasional nic freeze?

Sincerely,

Lund
