>Description:
Trying to mount an RCA Lyra (MC2020A model according to the back) as a
umass device doesn't work.  (The Lyra is a low-end personal audio device,
mine has 512MB of flash on board, plus it accepts CF cards to expand its
capabilities.)

If I try to mount it, the process takes forever, and then fails, viz.:

[root@arcusv:root]# mount_msdos -o ro /dev/sd0a /mnt
mount_msdos: /dev/sd0a on /mnt: Device not configured

Trying to run disklabel sd0 seems to just run forever, until I send it a
signal to hang up.

Particulars that show up in dmesg are:

umass0 at uhub0 port 1 configuration 1 interface 0
umass0: THOMSON RCA_MPCF2472_US, rev 1.10/10.01, addr 2
umass0: using SCSI over Bulk-Only

sd0: I/O error reading block zero

(... and so on, until mount gives up.)

Note that the geometry that's fabricated is incorrect, it thinks it
only has 122MB instead of 512MB.
>How-To-Repeat:
Try mounting one of these critters.
