[PATCH] provide MODALIAS= enviroment variable to autoload ieee1394 modules via udev
https://bugzilla.novell.com/show_bug.cgi?id=103746
Old 2.6.13 hotplug enviroment for 'plug in firewire disk' event:
==> debug.01139.ieee1394.add.8211 <==
set -- ieee1394
UDEV_LOG='7'
ACTION='add'
DEVPATH='/class/ieee1394/00010410100036e0-0'
SUBSYSTEM='ieee1394'
SEQNUM='1139'
PHYSDEVPATH='/devices/pci0001:10/0001:10:0d.0/0001:11:0a.0/fw-host0/00010410100036e0/00010410100036e0-0'
PHYSDEVBUS='ieee1394'
VENDOR_ID='000000'
MODEL_ID='001010'
GUID='00010410100036e0'
SPECIFIER_ID='00609e'
VERSION='010483'
UDEVD_EVENT='1'
Module spb2 is not loaded.
grep sbp2 /lib/modules/2.6.13-20050901172817-default/modules.alias
alias ieee1394:ven*mo*sp0000609Ever00010483* sbp2
printf 'ieee1394:ven%08Xmo%08Xsp%08Xver%08X\n' '0x000000' '0x001010' '0x00609e' '0x010483'

modprobe -v ieee1394:ven00000000mo00001010sp0000609Ever00010483
insmod /lib/modules/2.6.13-20050901172817-default/kernel/drivers/ieee1394/sbp2.ko
Providing a MODALIAS= enviroment variable with the content above will fix it.
