Well, that's changed...I *have* tested it now on an X6DHP box running
SuSE Enterprise 9 with the 2.6.13-rc3-mm3 kernel (plus the lm93 driver)
and lm_sensors 2.9.1.  When loaded normally, the driver puts these
messages into the system log:

Aug  2 12:53:58 cr0219en kernel: i801_smbus 0000:00:1f.3:
Aug  2 12:53:58 cr0219en kernel: lm93 0-002e: lm93: block read data
failed, command 0xf5.

(This gets repeated over and over, with the "command" value in the
message changing to values like 0xf9, 0xf6, 0xf7, and 0xf4.)

And, under these circumstances, the sensor readings are essentially
blank; all 0's for voltage, all -1's for fan speed, and all 0's for

I unloaded the module and reloaded it with disable_block=1 (thank you
Mark for thinking of that option!), and the sensor readings looked more

Any idea what's going on here?  Obviously, the block operations in the
driver are hosed somehow, I'm just not sure where to look for the source
of the hosation...
