#70 instability under 2.6.0

[Anonymous]

problem 1:
An external 1394 disk enclosure must be power cycled at
each reboot. Until it is power cycled the device
registers SBP login failures and protocol errors.
Power cycling the device once the system is up (seems)
to correct the issue. This would seem to indicate the
need for a driver level reset of all chained devices
when the driver modules are loaded or in reboot.

problem 2:
Under 2.6.0 the 1394 specific /proc files don't exist.
I cannot find /proc/bus/i1394 or /proc/scsi/sbp2.

problem 3:
ohci1394 does not correctly register itself as being in
use under lsmod when accessing a 1394 connected disk.
This allows the module to be inadvertantly removed even
if 1394 devices are being used.

2.6.0

3.3

ADS Dual Link Drive Kit (XLS-185)
