X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sun, 31 Oct 2004 16:55:39 -0000 After upgrading from 5.2.1 to 5.3-RC1 (including a recompile of all ports), I noticed my system locking up when there was a high network load. A common way to reproduce this is to run a BiTTorrent client and, say, copy a file to another local machine over NFS. The computer does not respond to pings or any key presses. I'm using the lnc(4) driver for an AMD PCnet PCI ethernet card (exact model escapes me) [Am79C970/1/2/3/5/6 PCnet LANCE PCI Ethernet Controller]. (I'm aware of the pcn(4) driver, but cannot get it to recognize the card). I can reproduce this with both the 4BSD and ULE schedulers, if that matters. All relevant sysctl variables are defaults. Is this a known issue? Any ideas? Thanks. -- Joshua Beard % echo "%m=oc%.%tr=eb%we=h@hs%%oj%"|sed 's/\%//g; s/=//g'|rev PGP Key: http://www.hewbert.com/pgp.asc
