Hello,
I found problems using 2.6.38.1 (2.6.38, too) on DNS323 Rev. B1
(orion5x) - seems to be an I2C-Bus- or RTC-driver problem.

This problem does not occur using original firmware (moddified 2.6.16
Kernel).
Fan, RTC and temp. sensors are working fine with original firmware.

The formerly found bug seems to be introduced with the RTC-rework starting with kernel 2.6.38.
It seems to be NOT a bug of I2C- or LM75-driver!
The bug starts with kernel 2.6.38 and is still there in 2.6.38.2.
Kernel 2.6.37.6 runs fine!!!! No RTC-bug here!!!
