One of our M5's running 5.5R1.2 is logging this every couple of hours:

Jul 13 19:47:02 lj2-lo0.router.amis.net feb DS1625: config error on temp read (0x4/0x48/0x8a)
Jul 13 19:47:02 lj2-lo0.router.amis.net feb CM: Could not read PS Intake temperature sensor: generic failure
Jul 13 19:47:02 lj2-lo0.router.amis.net craftd[2620]: forwarding display request to chassisd: type = 4, subtype = 43
Jul 13 19:47:02 lj2-lo0.router.amis.net alarmd[2619]: Alarm set: Temp sensor color=RED, class=CHASSIS, reason=PS Intake temperature sensor failed.
Jul 13 19:47:03 lj2-lo0.router.amis.net feb CM: ALARM SET: (Major) PS Intake temperature sensor failed.
Jul 13 19:47:40 lj2-lo0.router.amis.net craftd[2620]: forwarding display request to chassisd: type = 4, subtype = 44
Jul 13 19:47:40 lj2-lo0.router.amis.net alarmd[2619]: Alarm cleared: Temp sensor color=RED, class=CHASSIS, reason=PS Intake temperature sensor failed.
Jul 13 19:47:40 lj2-lo0.router.amis.net feb CM: ALARM CLEAR: PS Intake temperature sensor failed.

Any idea what is going on here? Messages suggest hardware problem, so I'm
wondering if anyone has seen something simmilar and traced the problem to
either hardware or software.

Hi Blaz --

This is a software bug. You can safely ignore these messages as long as the
temperature sensor failure alarm is transient (i.e., lasts no more than a
minute
or two).

This is fixed in 5.5R3 and higher versions of Junos. This bug is described
in PR/28187.
