: Have anyone seen bad performance when using umass devices (external

I don't see it.

But I'm not using a usb mouse/keyboard...  Are you?

: The reason I ask is that I have this machine[1] which is both a test
: workstation, and cheap-ass fileserver. I am using external usb drives
: for storage (it was the cheapest option when I set this up).

: Yes, there is a firewire drive in there too.

: The machine currently runs FreeBSD 6.4-stable / amd64, and have run

: The machine have always been in X when it is up (I use XFce) and this hasn't created any problems that I have noticed.
: However, after I upgraded Xorg to 7.4, I get lots of these messages in /var/log/messages if I try to
: do a simple 'ls' on any filesystem on a usb drive:

: and the 'ls' takes several minutes to complete.
: 
: Notice that the messages mention all umass drives (umass0 - umass3), even if I only do an ls on one of them.
: Also notice that the firewire drive is absent fom any messages.
: Note: hal is NOT running on this machine.
: 
: What is my workaround? Reboot the machine (needing a forced reset, as the machine hangs on shutdown
: after the umass errors), let fsck do its thing and then don't start Xorg. But this is no solution.
: 
: The funny thing is that It worked find before I upgraded Xorg from 7.3.2 to 7.4...
: 
: Any hints on how I can debug this?

: More info: FreeBSD work log[2], dmesg output normal[3] and verbose[4].
