Normally I build VMware ESXi servers with enterprise-class WD SATA drives and
I/O performance in FreeBSD VMs on the servers is fine.
Whenever I build a VMware ESXi server with a RAID controller, IO performance is
awful in FreeBSD VMs. I've previously seen this effect with VMware ESXi 3ware

Still working this problem I've previously mentioned, and my working theory now
is a race between catchpacket() and this code in bpfread():

To close PR bin/83340, I have this change worked up to resolve memory
allocation failure handling and avoid creating bad entries in the grp list due
to memory allocation failures while building a new entry.

On a FreeBSD 7.1 SCHED_ULE kernel, I have a large number of files opened and

Perhaps such messages could go through a rate limiter mechanism similar to
that now used by the network interfaces.
I am not certain whether this addition would affect the TrustedBSD work,
either.

Does anyone happen to have patches for FreeBSD 4.2 to make the pcm driver
drive the sound device in the Dell Latitude CPt (identified as vendor

provide a pointer to them?

rhaps the Appletalk daemon becomes confused when tcpdump puts the
Ethernet interface into promiscuous mode. It may be that the daemon
expects to see only the Appletalk traffic directed to it, and seeing *all*
Appletalk traffic on the wire makes it go nuts.

Anyway, the card is mostly the same as the Vortex (if_vx.c driver) but
