Hello, I have suse 9.3 on Athlon64 box and see strange system freezes. System is running as nfs- and ftp-server (vsftpd) when I connect from another machine with lftp, I can change into the directory, do ls -al etc. but as soon as I fire a "mirror -vv" the server freezes hard! Cursor stops blinking, unable to switch tty, no ssh access, no ctrl-alt-del etc... Alt-SysRq-b is the "softest" way to get out of this. The funny thing is: if I ssh into the box before starting the ftp-session, everything is fine! Same problem with NFS! Tried it again and again and again ... absolutely reproducible! Disabled acpi 2.0 / apm / apic in BIOS, even stopped rcpowersaved, because I found some article about this ... but no luck. So I setup a second box with exactly the same hardware configuration (just slightly different PSU, but still 550W) and yes: I get the same behavior. Any idea ? I really appreciate any of your help! Best regards, Burkhard
