I have a number of machines running 3.2-STABLE with no problem, except one, an "old" Pentium 200. It has an Intel PRO/100+ Server Adapter (fxp0), two IDE disks, and 1 IDE CDROM drive (dmesg below). This also was happening in later builds of 3.1-STABLE. Large transfers, such as an NFS-mount installworld or a ftp get of a file over approx 1MB, will stall regularly and indefinately. No other operation appears to be affected and I can start another ssh session with the "stalled" machine. How should I go about debugging this problem? thanks, kenn ---8<--- May 16 23:07:50 andover /kernel: Copyright (c) 1992-1999 FreeBSD Inc.
