I use 'dd' to create empty files to place on the public ftp server.
I created files of the following sizes: 1M, 2M, 3M, 4M, 5M, 10M, 20M, 30M, 40M, 50M, 100M.
Shortly after creating the 100M file, the ssh session hangs. When checked the console, I found that the system wrote something about "Reset detected on CPU2, cannot dump because no device was specified... Press any key to reboot"
When tried to reboot by pressing any key, found that the system does not respond to the keyborad...
>How-To-Repeat:
# dd if=/dev/zero of="100M-empty-file" bs=100M count=1
>Fix:
Do not use 'dd' and the system works more than fine!
