I get pmap related vm crashes or corruption, relating in filesystem corruption. I had about 3-4 different panics. Mozilla build tends to prefer "panic: bad link count", openoffice prefers page faults in ffs code ;) But these options here are enabled: options DISABLE_PSE options DISABLE_PG_G Are there any options I could also add and try ? Page coloring etc ? You remember, I had SIG4 and SIG11 over and over until I used these options. The builds run fine by then, I had no panics at all anymore. I was happy. After gcc32 was imported. I got panics over and over. I looked carefuly that no -march was used, so that this could be the reason. I use now this option to get a panic even faster ( and to get a lot smaller dumps of course ) ;) options MAXMEM="(128*1024)" It cannot be hardware. I've preplaced everthing on this box, including the motherboard. Michael Reifenberger has the same symptoms. I bet he has also a PIV. This is now a PIV machine (2,26 Ghz) with 1GB Ram, and as you see only 128MB active at the moment. I have kerneldumps available. If requested, I can compress them and make available on projects.imp.ch Martin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
