Any service mods?  Or just straight GE and/or TE?

SXH3a/4 spurious interrupts raised on the following events:

Archive feature triggered on the write mem
L3 port-channel bundle member interface addition with the IP address
still configured on the member interface (symptoms include: freeze up
for 30 seconds, spurious interrupts with the path to pagp module).

SXI is free of these defects and overall appears to be running great.

SXH2 has some critical NetFlow bugs. Cisco said disable "ip flow
ingress" on all interfaces as a work-around. Unfortunately we have
experienced other crashes too, without identifying root-cause.

At this point we have completed the migration to SXI, so I'm trying to
forget all about SXH.

(I should probably mention this is modular IOS.)
