>Description:
when i attach my mp3 player everything works fine and i can mount it
without any problems:
umass0: CREATIVE Zen Nano Plus, rev 2.00/11.23, addr 3
umass0: SCSI over Bulk-Only; quirks = 0x0000
umass0:4:0:-1: Attached to scbus4
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <CREATIVE Zen Nano Plus 1123> Removable Direct Access SCSI-4 device
da0: 1.000MB/s transfers
da0: 489MB (250432 2048 byte sectors: 64H 32S/T 122C)
however....when i try to copy files onto the umass device (this also
happens not only with my mp3 player but other umass devices) and my
system is performing a lot of tasks the data transfer will stall.
if apart from `cp` no other I/O intensive apps are running the transfer
to umass devices succeedes. so maybe there's a problem with the
scheduler (i'm using ULE).
this is the error i'm getting:
umass0: BBB reset failed, STALLED
umass0: BBB bulk-in clear stall failed, STALLED
umass0: BBB bulk-out clear stall failed, STALLED
umass0: BBB reset failed, STALLED
umass0: BBB bulk-in clear stall failed, STALLED
umass0: BBB bulk-out clear stall failed, STALLED
umass0: BBB reset failed, STALLED
umass0: BBB bulk-in clear stall failed, STALLED
umass0: BBB bulk-out clear stall failed, STALLED
umass0: BBB reset failed, STALLED
umass0: BBB bulk-in clear stall failed, STALLED
umass0: BBB bulk-out clear stall failed, STALLED
umass0: BBB reset failed, STALLED
umass0: BBB bulk-in clear stall failed, STALLED
umass0: BBB bulk-out clear stall failed, STALLED
continued by a lot of
g_vfs_done():da0s1[WRITE(offset=32768, length=4096)]error = 5
g_vfs_done():da0s1[WRITE(offset=45056, length=4096)]error = 5
g_vfs_done():da0s1[WRITE(offset=98304, length=4096)]error = 5
g_vfs_done():da0s1[WRITE(offset=159744, length=4096)]error = 5
g_vfs_done():da0s1[WRITE(offset=172032, length=4096)]error = 5
g_vfs_done():da0s1[WRITE(offset=225280, length=4096)]error = 5
g_vfs_done():da0s1[WRITE(offset=119721984, length=8192)]error = 5
....
....
etc.
eventually the whole sysmtem becomes unstable and most of the apps i'm
running don't respond any longer. unmounting the umass device isn't
prossible and unplugging the devices crashes the whole system.
i've attached my KERNEL CONF file below.
cheers.
