Hi,
I'm not sure if this is an USB issue or not. If you get READ/WRITE errors and
the drive simply dies then it might be the case. Else it is a system issue.
There are quirks for mass storage which you can add to
sys/dev/usb/storage/umass.c .

Is something new in 8.0 making disk partition schema changed?

Subject: 8.0-RC3 USB lock up on mounting two partitions from one USB drive
When mounting two partitions from a USB dirve, it can cause the drive
access lock up for a long time. Details:
Terminal 1 --
term1# mount /dev/da0s3d /mnt
term1# cd /mnt ; rm -fr *
when rm starts, go to terminal 2 and do:
term2# mount /dev/da0s3e /dist ### this will hanging for a long time and
USB hard drive activity light is off. After more than 1-2 minutes, mount
returns, and the drive activity light is blinking, thus removing is going
on.
term2# ls /dist ### this will cause dUSB dirve hanging again -- no
avtivity. Similarly, ls will finish in a couple of miniutes or longer, the
rm command continues; but for a while, the drive activity will stop again.
Reboot machine, repeat the above steps, and result will be the same. Reboot
machine again, and just mount one partition, then doing "rm -rf *" without
involve the second partition, rm will finish quickly.
Has anyone obseved this behave on 8.0-RC?
