Is support forthcoming? We have 2 Dell PowerEdge 1850 servers which have the e7520 chipset. They hang consistently in 4.10-RELEASE and below whenever there is high network or disk utilization. We have not been able to get any debugging info. After upgrading to 4.10-STABLE a couple of weeks ago, they no longer hang, but they are _really_ slow to perform network and disk operations. They work fine in FreeBSD 5.3, but unfortunately our applications do not run without recompiling. We do not want to change our environment to support different binaries for different machines, and we don't want to use 5.X in production until it is STABLE. I want to echo the above question. Are there patches available or forthcoming to fix the problems with the e7520? Thanks, - Rob Watt
