Hello, i'd like to inform a problem when dettaching an external 1TB USB
disk drive , the system just freezes, i can't type anything. Also It
stops responding to ping.
If i don't unplug it then i can use the disk normally, i can copy and
delete files with no problem. But as soon as i unplug the USB cord, the
machine freezes.
I've tested it on several machines, different OpenBSD versions starting
from 4.3, i'm not asking for support, i know old OpenBSD versions are no
longer supported, but this seemed pretty odd, i suppose that plugging
and unplugging a USB disk should not cause any problems on any OS version.
These are the lines on dmesg about this disk:
