Nicolas, can you please try with lm_sensors SVN:
Comment 6 Nicolas Mailhot 2007-03-03 02:01:13 UTC
Ok, will try. Is this a 2.10.3 prerelease snapshot?
Comment 7 Jean Delvare 2007-03-03 02:11:28 UTC
Sort of, yeah, although the 2.10.3 release isn't schedule yet.

The "it8712-i2c-9191-290" name is unexpected, it should be "it8712-isa-0290" so
indeed something's broken. I'll try to reproduce it locally.

In the meantime, can you please test 2.6.21-rc2 (non-mm) and confirm that it
works OK?
Comment 11 Nicolas Mailhot 2007-03-03 02:34:12 UTC
as soon as I get ivtv working on the mm one :)
Comment 12 Nicolas Mailhot 2007-03-03 04:27:58 UTC
I can confirm that's a -mm problem. Mainline (2.6.21-rc2.git3) is fine (but
lacks ivtv):

Please apply this patch to your SVN snapshot of lm_sensors and try again. It
should make "sensors" work fine again.
Comment 16 Nicolas Mailhot 2007-03-03 07:42:27 UTC
The patch works, thanks
Comment 17 Jean Delvare 2007-03-03 07:59:17 UTC
Great, thanks for testing. Patch committed to the lm_sensors SVN repository. Now
I need to schedule the release of 2.10.3.
