This is a regression from 2.6.29. Microcode spews the following WARNING
multiple times during boot:

------------[ cut here ]------------
WARNING: at fs/sysfs/group.c:138 sysfs_remove_group+0xeb/0xf0()
Hardware name: sysfs group ffffffffa0209700 not found for
kobject 'cpu0'

Update: Regression occurs in 2.6.30-rc2.

I've now reproduced this on ICH9/Core2 as well as ICH10/Nahelem.
Hi,


the following patch should eliminate the problem (and revert to the old behavior that was altered by Rusty's patch).

Jeff, did this do the trick for you?

Yes -- but I worry about keeping sysfs files around too long?

Jeff
