Sorry, the file reportbug placed in /tmp was some kind of weird also.

The short version is, frequent disconnects using iwlfifi device:

$ lspci -nnk | grep Shiloh
02:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 5100 AGN 
[Shiloh] Network Connection [8086:4237]

...seem to be fixed by masking systemd-rfkill service and target.
FYI

Thanks,
