USB Flash disk on FreeBSD 6

[Cesar]

Hi,

    Anyone know if FreeBSD 6.x have problems with usb flash disks?
    I have a mini-freebsd build running on some flash disks with FreeBSD 
5.3, last week I changed to FreeBSD 6.0 and my flash disks started to show a 
lot of errors. I tried the 6.1 STABLE too, but no lucky.

Flash Disk Info:

da0 at umass-sim0 bus 0 target 0 lun 0
da0: <USB 2.0 Flash Disk 0.00> Removable Direct Access SCSI-2 device
da0: 40.000MB/s transfers
da0: 246MB (504832 512 byte sectors: 64H 32S/T 246C)

Errors on FreeBSD 6.x
g_vfs_done():da0a[WRITE(offset=65536, length=2048)]error = 5
g_vfs_done():da0a[WRITE(offset=147456, length=8192)]error = 5
g_vfs_done():da0a[WRITE(offset=3055616, length=1024)]error = 5
g_vfs_done():da0a[WRITE(offset=3576832, length=1024)]error = 5
g_vfs_done():da0a[WRITE(offset=94797824, length=8192)]error = 5
g_vfs_done():da0a[WRITE(offset=94806016, length=8192)]error = 5
[...]

    Any idea?

    PS. I have more then 20 flash disks running fbsd 5.3 without problems. I 
installed like 5 flash disks with fbsd 6x and all 5 show those errors.


Thanks in advance.
