Hi,

I have a strange issue with 4.17 kernels:

When I run my scanner (Fujitsu fi-4220C2) using gscan2pdf/sane, the system reboots 
spontaneously after the first page, there is no log entry, no Oops, nothing, here are lines 
from kern.log (timestamps are too far apart for a spontaneous reboot):

Aug 22 18:26:33 b370 kernel: [ 3118.972889] perf: interrupt took too long (3993 > 3976), 
lowering kernel.perf_event_max_sample_rate to 50000
Aug 22 18:42:27 b370 kernel: [    0.000000] Linux version 4.17.0-3-amd64 (debian-
kernel@lists.debian.org) (gcc version 7.3.0 (Debian 7.3.0-28)) #1 SMP Debian 4.17.17-1 
(2018-08-18)

The issue seems to be 100% reproducible with the 4.17 kernels I tried on my system:

root@b370:~# dpkg --get-selections |grep linux-image-4.17 

Any idea what happens here is welcome.

Should I open a bug report? If yes, which data should I include?

Thanks
Rainer
