Re: Fwd: Re: [linux-usb-devel] USB Storage oops in 2.5.69-bk8

[Mike Anderson <andmike@us.ibm.com>]

This might be a case that the scsi_error handler never reclaimed or
canceled the command (i.e., this is a lost command) and probably should
not update the fields.

Could you get me a little more data on what the error handler actions
where by doing the following:
	1.) Ensure SCSI logging is enabled in your config.
	CONFIG_SCSI_LOGGING=y.

	2.) Prior to the mount of the Compact Flash card.
	echo "scsi log error 4" > /proc/scsi/scsi

	If this is getting set dmesg should give a line that scsi
	logging level set to ...

	3.) Mount the Compact Flash card and send me the output when it
	fails.

Thanks,
