freebsd-stable Digest, Vol 57, Issue 3 - umass no working after mfc

[Marc Santhoff]

Hi!

Some more information:

I gave the USB stick the chance to think about it by forgetting to plug
it off and this happens after some minutes:

<syslog>
umass0: USB Flash Disk, rev 2.00/2.00, addr 2, SCSI over Bulk-Only
umass0:1:0:-1: Attached to scbus1 as device 0
usb_block_allocmem: in interrupt context, size=4096

da0: 650KB/s transfers
da0: 62MB (128000 512 byte sectors: 64H 32S/T 62C)
</syslog>

Appears to me as if this is some sort of timing problem or the like ...

The /dev/da0 device appears at the bus:

# usbdevs -v

Controller /dev/usb0:
addr 1: full speed, self powered, config 1, OHCI root hub(0x0000),
(0x10de)(0x0000), rev 1.00
 port 1 powered
 port 2 addr 2: full speed, power 200 mA, config 1, Flash Disk(0x2168),
USB(0x0ea0), rev 2.00
 port 3 powered

# camcontrol devlist

<PLEXTOR CD-ROM PX-40TS 1.11>      at scbus0 target 2 lun 0 (pass0,cd0)
<Sharkoon Flexi-Drive 2.00>        at scbus1 target 0 lun 0 (da0,pass1)

but mounting it fails with this syslog output:

<syslog>
usb_block_allocmem: in interrupt context, size=4096
usb_block_allocmem: in interrupt context, failed
umass0: BBB reset failed, TIMEOUT
usb_block_allocmem: in interrupt context, size=4096
usb_block_allocmem: in interrupt context, failed
umass0: BBB reset failed, TIMEOUT

usb_block_allocmem: in interrupt context, failed
umass0: BBB reset failed, TIMEOUT

usb_block_allocmem: in interrupt context, failed
umass0: BBB reset failed, TIMEOUT
da0: reading primary partition table: error reading fsbn 0
</syslog>

The last line might result from the fact that I forgot to tell mount
that it should use "-r -t msdos" in my excitement (write protect switch
set to "on") ... after that the device was busy until I gave up.

Any change in state takes long time, approx. between one to three
minutes.

Hopefully this helps catching some errors,
Marc
