Hello list, I'm having serious trouble with the following config: * asus A8V mobo - bios 1007 - * athlon 64 3500 (90nm) * 2*512Mb ram (3-3-3-8) * system disc on u320scsi (tekram dc390u4b/w card) maxtor 15k atlas 36GB * 3 data disks (maxtor ide 120GB) on hdb,hdc,hdd * no overclocking or special settings * suse 9.2 x86_64 with latest patches * marvell (on board) gigabit chip (sk98lin driver), connected to a dlink gigabit switch (dgs-1008d); At the present time, the purpose of this machine is to be tested before going into production. Here are the symptoms: - the system totally hangs when the vsftpd server (started thru xinetd) is called from the outside (32 bits suse9.2 boxes); reset is the only solution... - Nothing in /var/log/messages and no crash dump anywhere on disk - I've removed vsftpd and installed pure-ftpd instead -> This time, ftp transfers are ok (no more freeze) - Started nfs server on the box and created a share; when I try to mount the nfs share from a remote 32 bits box (asus A7n8x with marvell gigabit chip), the 64 bits system is again totally frozen ! Except that, the system is running like a race car (no network problem when I initiate network from the box - internet browsing is perfect)! Any suggestion, experience, clue, tip, etc... is welcome, 'cause I'm stuck ! cheers, fabrice
