Bus specific file unavailable

Bus specific file unavailable

[Arthur Hartwig]

My Gentoo 2005.1 (Linux 2.6.12) system has been reporting on startup:

wait_for_sysfs[7376]: either wait_for_sysfs (udev 045) needs an update 
to handle the device '/devices/pci0000:00/0000:04.0/i2c-0/0-0048' 
properly (bus specific file unavailable) or the sysfs-support of your 
device's driver need to be fixed, please report to 
<linux-hotplug-devel@lists.sourceforge.net>

I get the same thing reported twice more for devices "49" and '2d'  
('49' and '2d' replace the '48' in the above message).

after logging in I see":
# more /sys/bus/i2c/devices/0-002d/name
as99127f
# more /sys/bus/i2c/devices/0-0048/name
as99127f    subclient
# more /sys/bus/i2c/devices/0-0049/name
as99127f    subclient

I am happy to provide any additional information you might require.

Arthur

Update your udev! Especially if you run a recent kernel. Your combination of
udev and the kernel will not work correctly.
