I'm running Solaris 9 on a Dell GX260 with Intel NIC chips on the motherboard
(equiv to an Intel Pro/1000 card and using the latest INTCGigaE drivers from
Intel.)
The current recommended patch set makes the PC act in a very strange manner.
The kernel CPU goes to about 50% and stays there and network connections are
VERY slow. If you ping the system from another machine you can watch the
ping times slowly increment from sub-millisecond response to a 1 second
response in 10 or 20 mSec jumps. When it hits 1 second the time starts from
a very low value again. There is also a 5% packet loss. Normally pings on
this network will run in sub-millisecond times and zero packet loss.

I've tracked the problem down to something in the 112234 series of Kernel
patches. The 112234-08 version works OK, the 112234-12 (and newest) version
shows the problem.
Has anybody already worked out what is happening here?
Thanks, summary will follow.
