Bug#401916: Bug 401916: analysis and suggested solution

Bonsoir David!

ok back after reading some code. :)

Quoting David Härdeman <david@hardeman.nu>:

yup ack.

i'll apply tomorrow and look to push that for 0.85f

hmm this seems to affect any modern board,
so urrgs.
but your grep on the usb_storage thread was not successfull,
so maybe we need here build depend logic?!?

ack, but not for etch:
The relevant commit happend for 2.6.20 with the note:
    "This patch only handles drivers which call scsi_scan_host.
     Fibre Channel, SAS, SATA, USB and Firewire all need additional work."

so it would already be of a help for uname = 2.6.20.
willy was pushing this work, so we'd have the expertise for a postetch
kernel fixes.

> How would MODULES=MOST create stuff under /dev then?
what about static dev.. ;)

happy night
