Yaniv, is PF(4) used on your system with em interfaces?

I tested another Sun X4200 with em(4) interfaces and I have *NO* problem with
data corruption!

On this system I checked:
10.1-STABLE r280356 with uptime 231 days
10.2-STABLE r290385 with uptime 8 days

Sun X4200 have same to X4100 motherboard, BIOS patch level and network
interfaces.
Only ONE difference - on X4200 PF functionality was disabled.

After a week I can enable PF on my X4200 and recheck.

Also, on X4100 I got data corruption several times immediately after system's
boot.
