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 th= e 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 bzip= 2 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 ?
