The problem is not when the card is initially installed, but minutes to hours later. The time delay depend on the network it is on, and varies fairly widely. The delay only occurs when I type quickly (my typing speed is 5-8 presses per second) Case #1: 30-40 packet per second on network, minimal network usage Time delay: 8 minutes - 1 hour Case #2: <.8 packets per second, more extensive network usage Time delay: 4+ hours Case #3: <.8 packets per second background, LARGE network usage With my computer sending ~200 packets per second (using both BPF to receive & raw sockets to send), the machine becomes practically unusable within a minute. The problem is intermittant, with no pattern I can recognize on whether, but it seems to generally last 5-10 minutes. I use both BPF and raw sockets, which is probably a little unusual, but whether or not I'm using them at the time does not seem to matter. My uptime is pegged at 0.00. The keyboard also losses key presses if I continue to type quickly, but as they do not appear to be lost if I type slowly, this is probably due to the keyboard buffer becoming full, not a direct problem. Bucky key releases appear to be lost as well. Mouse is still responsive. >How-To-Repeat: I have not tested this on similar laptops, but generically, plug in an PCMCIA Ethernet card and send packets quickly. >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
