There are TWO separate problems here, both of which will manifest as lost sync and the `out-of-sync' error message. One of them is due to the use of KVM boxes. The other isn't - it occurs, for example, on my Compaq laptop using the built-in touchpad, and has affected other people as well. I maintain that the latter is due to a bug or oversight in the psm driver, as tweaking the code in this driver has allowed me to circumvent the problem. However, my tweaks deal with the symptoms; I have not identified the underlying cause other than that it seems to be related to spurious data (rather than lost data). gram -- Dr Graham Wheeler E-mail: gram@cequrux.com Director, Research and Development WWW: http://www.cequrux.com CEQURUX Technologies Phone: +27(21)423-6065 Firewalls/VPN Specialists Fax: +27(21)424-3656 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
