Hi, I'm working with server based on Intel 7520 (Lindenhurst) chipset. This uses the i2c-i801 bus driver. An lm93 is attached to this bus. If I load the lm93 in it's default mode, which "allows SMBus block data transactions if the host supports them", it takes a long time for sensors to run. This is the output of "time": real 0m10.901s user 0m0.010s sys 0m0.010s If the lm93 is loaded with it's disable_block mode, which disables data block transactions, the operation is much faster: real 0m1.261s user 0m0.010s sys 0m0.010s In both cases, there are no errors logged to dmesg or /var/log/messages. The output is correct in both cases. The data block transaction mode just takes a lot longer to complete. Any ideas?? David
