MTP008 Tyan Thunder 2510 sensors crash
What I mean by crash is that sensors correctly displays values for a few times but then stops doing
so.
This is also mentioned in the FAQ
############
>From the FAQ:
############
4.17C "...Also, MTP008 chips seem to randomly refuse to respond, for unknown reasons. You can see
this as 'XX' entries in i2cdump..."
Is there anything that can be done?
Example output from proc:
[root at neptune mtp008-i2c-0-2c]# pwd
/proc/sys/dev/sensors/mtp008-i2c-0-2c
[root at neptune mtp008-i2c-0-2c]# less temp1
-1.0 -1.0 -1.0
[root at neptune mtp008-i2c-0-2c]# less fan1
0 0
I examined tickets for the Tyan 2510 but did not find any answers. Please let me know if there is
anything I can do to debug and ultimately fix this problem.
Thanks in advance
