kernel panic on 6.1-PRERELEASE with Lexar Jumpdrive2

Hello,

I've been having kernel panics when I use one particular USB flash drive
(LEXAR MEDIA JUMPDRIVE2, rev 2.00/1.25, addr 2) with FreeBSD
6.1-PRERELEASE (See [1] below). All I have to do to get the kernel to 
panic is to insert and remove the drive from the USB port 2 or 3 times 
(without mounting the drive. Entries in /dev do not get created. See [2] 
for error I get when I insert the drive and [3] for the error I get when 
I remove the drive.)

This problem happens only if the "ehci" device is enabled in the
kernel
(GENERIC has it enabled by default). If I comment out the "ehci"
device
and use only the "uhci" device, then I get a device entry in /dev and
I'm
able to mount the flash drive just fine and, insert and remove as many
times as I like without any problems. 

So I suspect that it is a problem with the "ehci" driver.
Unfortunately
I'm not being able to get a crash dump as the system starts dumping and
then freezes.

I wanted to see if there is anybody on the list who has experienced
anything similar.

I have 2 other newer flash drives and they seem to work fine. The system
seems to panic only when I use this particular flash drive. The flash
drive is empty and I'm able to mount it fine if I use only the
"uhci"
driver.

regards,
joseph

You left out details of the panic and backtrace.

Note that echi(4) states:
BUGS
     The driver is not finished and is quite buggy.

Try adding the following options so you can get backtraces without dumps:
options         KDB
options         KDB_TRACE
options         DDB
>I have 2 other newer flash drives and they seem to work fine.
Which suggests it needs a quirk of some sort.>umass0: at uhub0 port 5 (addr 2) disconnected

I've seen similar behaviour on ulpt as well.  The USB subsystem does
not appear to recover from errors on the hardware side.  In my case,
that USB port wedges and cannot be used until the system is reset
(though other ports are OK).
