Hi, I have observed a strange behaviour on the Marvell Discovery: I have a memory disk for /etc and /opt: /dev/md0 on /etc (ufs, local) /dev/md1 on /opt (ufs, local) When I copy files to that disk, which are larger than 0x1ffff (131071 bytes), these files differ from the original. This occurs only when copying to md. Kernel is: FreeBSD discovery1 8.0-STABLE FreeBSD 8.0-STABLE #0 r206836: Mon Apr 19 12:53:42 CEST 2010 root@vbcspc12.bcs.brunel.local:/usr/obj/arm/root/ARM/8/sys/DB-78XXX arm I had a look into the damaged file and found some excerpts from files located in /etc (which is also in RAM): ------------------------------------------------------------ passwd: compat passwd_compat: nis shells: files ----------------------------------------------------------------- ... ----------------------------------------------------------------- staff:*:20: sshd:*:22: smmsp:*:25: mailnull:*:26: guest:*:3-��� ------------------------------------------------------------------ Looks as if the CPU has problems accessing the RAM. I have already changed the RAM, so I don't think it's a hardware problem. Any idea? Matthiashome | help
