when i started to ftp and csup at the same time this error got into my dmesg.
Could you please check at your end also.
machine is alive after this - but it's a bit annoying
>How-To-Repeat:
try to copy to /root with sftp and csup at the same time.
HW is 3GB memory, areca 1120 and k8 master f mobo
>Fix:
if i knew i'd fix it.
