I have seen segfaults when using a huge amount of RAM, if I do not either disable the PSE bit (4M pages), or preallocate enough kernel memory to cause the PTD's to be thrashed out by other PTD's (e.g. set MAXFILES to 120000). FreeBSD appears to have a situation in which CR3 is not reloaded, and the board somehow ignores the INVLTLB with the PG_G bit set. As I said: you can work around this, though. Oh, and be sure you are running the most recent BIOS. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
