I did try to reserve out of use 32MB of my 64MB memory for test purposes with the program main() { char *p; int i; p = malloc(10000000); i = mlock(p,10000000); sleep(1200); exit; } (Maybe not 100% same, I cannot use the disk at this moment :-( ) And intended to run it 3 times. I did run it as root one time! This got the whole machine down. At boot root mount OK, but fsck: /dev/sd0s1f. No such file or directory Can't stat /dev/sd0s1f same with /dev/sd01e mount -a: /dev/sd01f on /home: no such file or directory same with /dev/sd01e procfs: I/O error I have /home and /usr I did run same program with 1MB memory area and had no problems. It seemed to reserve the 1MB of RAM. I promise never to try this again. ;-) Can I somehow get these partitions mounted? Seppo PS. Is there some other safer method to disable big parts of RAM? I wanted to compare one 32MB Linux machine to my 64MB FreeBSD machine. I think, I cannot disable RAM in hardware, I have 2*32MB SIMMs. -- +-- Seppo Kallio ----- kallio@jyu.fi ---+ !
