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- ker...@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 -- Rainer Dorsch http://bokomoko.de/
