My guess would be the solaris driver: we use two such cards in a SS20
firewall, behind which are two U1's with hme's. When making full backups
to a machine on the other side of the firewall, the workload looks like
this:

load averages:  1.84,  1.71,  1.46
17:05:47 13 processes:  4 runnable, 8 sleeping, 1 on processor
CPU states:  0.1% user,  0.0% nice,  0.0% system, 99.8% interrupt,  0.1%
idle
Memory: 5108K Act, 2436K Inact, 132K Wired, 101M Free, 328M Swp free

This goes on for two straight *days* (48 hours). Our intranet is still
usable, you can browse the internet, irc, whatever. It just takes
around three minutes to connect to the firewall via ssh ;)

I would say they're stable.
