I'll also try the DISABLE_PSE and DISABLE_PG_G options. Please do these seperately. Changing the amount of RAM is only indicative, not diagnostic, so it's just additional information, if it does anything, instead of nothing. With Matt Dillon's changes to machdep.c to do auto-tuning, changing the amount of RAM is much less likely to work around the problem, unless you hit the stair function at just the right point. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
