8.0-RC USB/FS problem

Interesting now by some incident :-)
The single CPU machine (Intel P4) with 8.0 works fine on the USB drives
and the USB stick.
So, installed 8.0 on another AMD Turion64 HP Pavilion dv5210us Laptop,
it
comes the same problem -- accessing the USB hard drive causes system
panic
and reboot:
Took the previously dump/restored USB drive and mount it on this Laptop,
tried to remove the data before dump/restore, it crashed the system
after
hit ^C and unplugged USB hard drive when the LED on USB hard drive
becomes
solid red and spiting out numbers of lines Operation not permitted
(the user is root, so this means accessing hard drive is not possible):
rm: bin/... : Operation not permitted
......
A second try causes the system locks up After ^C.
So, try to re-partitioning the USB hard drive on AMD laptop and
dump/restore, partitioning passed, but dump/restore crashed.
Since hw.usb.umass.debug=-1 does not tell a USB problem beside the
RESET,
What other debug shall we turn on to analyze this problem.

Freshly installed 8.0-RELEASE on two differnt machines, and USB stick
work well so far, but the USB hard drive
still has crash on this SMP (4-core AMD phenom 9600) during the
dump/restore. I will try it on the single CPU
machine tomorrow.
Re-tested dump/restore with FreeBSD 6.3/6.4 on this SMP machine and they
are working well.
Also the another strange thing ocurred during the mount a partition on
/tmp, which ended with two /tmp,
and the last one mounted is on the top (the first should be hidden):

repeated a few time on following process and ithe crash happened at
different USB access phase at each time.

System crashed
The crash log is available at
http:/www.daemonfun.com/archives/pub/USB/crash1-reset.bz2
(All logs are based on hw.usb.umass.debug=-1)
After system reboot, and repeated above processes, the da0s3e was
mounted on /dist, but da0s3d cannot.
It tunred out that newfs fail inside labeling process in sysinstall.
Manually did newfs on da0s3d, and
it cannot be mounted on /mnt, but access to it caused crash.
The crash log is available at
http:/www.daemonfun.com/archives/pub/USB/newfs
Tried entire process again, this time, both partitons are formatted
(newfs) inside labaling process (sysinstall)
but crahsed system during dump/restore on da0s3e (/dist).
The crash log is available at
http:/www.daemonfun.com/archives/pub/USB/usb-log.crash2.bz2, which is
huge one.
It contains two parts, one dump/restore IDE to da0s3d (passed), and the
rest is dump/restore to da0s3e (crashed).
I am going to reinstall the system with the new ISO from Nov 21
8.0-RELEASE to see if anything will improve.

Hi,
Error 5 means IO error, so probably the transport layer, USB or lower,
is to
blame.
Some things to check:
1) Make sure the connection for your memory stick is Ok.
2) Make sure there is enough power for your memory stick.
Regarding memory sticks:
Other operating systems do a port bus reset when the device has a
problem. On
FreeBSD we just try a software reset via the control endpoint. I guess
that it
is a device problem you are seeing. The USB stack in FreeBSD is faster
than
the old one, and maybe the faster queueing of mass storage requests
trigger
some hidden bugs in your device.
When the problem happens try:
sysctl hw.usb.umass.debug=-1
--HPS
