if you read the Bug report you will see that the Nokia Engineer is asking for information. Please try and provide to help pin this down
=============from bug report==================
If the reboot happens with pre-installed or flashed 42-11, the most important
information is what this command outputs in XTerm:
If the reboot reason is "sw_rst" (instead of "32wd_to"), please provide also
output from this command:
(i.e. which crucial system service going down needed device reboot.)

This Xorg related sw_rst is most likely something we know about (hairy & very
rare SGX 3D driver memory management issue) and should be fixed in the next
If they continue after the next release, please provide us Xorg core-dumps with
Crash reporter (they could be useful also before that).
The 32wd_to (HW watchdog rebooting the device due to not it being updated) is
For 32wd_to reboots we need to know when exactly they occur:
- After device goes to sleep (screen blanks etc)?
- When device wakes / is woken up from sleep?
- When device is being used?
-> If yes, do the reboots happen also in offline mode?
If (32wd_to) reboots happen only when NOT using offline mode, we need to know
whether this happens only in some particular networking environment.
I.e. if you for example have reboots at home, do they happen somewhere else
(e.g. at work) where you use a different WLAN/phone access point (with
potentially different power management etc settings). If they happen only with
some specific access points, please file a separate bug about that and provide
the exact model of that access point and whether you've changed any of its
default settings (or device default connectivity settings).
