firewire scanner problems with 2.6.21.x kernels



An Epson 2450 Perfection scanner with both USB and firewire connections
works well using either type of connection when running FC6 [2.6.20.4
kernel].

When running fedora/rawhide [2.6.21.x kernel] the scanner works well
using the USB connection but has problems when using the firewire
connection.

With firewire and the 2.6.21.x kernel:
* scanner is recognized
* scan starts and then hangs

/var/log/messages indicate that connectivity/registration of the
firewire device has been lost:

Can anyone else verify this problem?
