[-- Attachment #1 --] Hi I have an HP DL380 quad core with 8GB of RAM and SAS disks in RAID, with freebsd 6 STABLE on it. Everything works fine, except for the RAM addressing problem: freebsd sees only 4GB. I know it have been discussed, but it could be a problem to me for running a 64bit compiled system; what is the stability of a kernel compiled with the PAE option? I've a kernel with no modules, and before trying PAE I would know for other people experiences... In particular I'm interested in the behavior of ciss, bce, em and usb stuff, and application like Perl, Ruby, PHP 5, MySQL server, heavy MAWK and bzip2 load. Also, if I boot a PAE kernel, in order to have all my RAM available, I have to set the hw.physmem variable to 8G ?
