You have an
lm(4) fan sensor, connected via an
iic(4) bus.
Code:
lm1 at iic0 addr 0x2c: W83627DHG
Going back up the tree, this is interconnected via pci0, and is apparently using the
pcixpm(4) driver to connect to the Intel SB600.
Looking through the CVS repository:
- There have been no apparent changes to lm driver modules since your October 15 kernel build, though I may have missed something when doing a quick search just now.
- There were no changes to any underlying i2c modules (sys/dev/i2c/*) during this same time period.
- sys/dev/pci/piixpm.c was last updated October 1, which was prior to your kernel build.
Recommendation:
Try a recent snapshot; my quick search may have missed a patch which affects your fan control path. (Plus, a recent snapshot is recommended prior to submitting any problem report.) Refer to the
Following -current FAQ for awareness of structural changes since October.
sysmerge(8) will automate most of these.
If your problem remains unresolved, I recommend that you submit an informal problem report to misc@, or a formal problem report to bugs@.
