I have a serious bug when using flashplayer in debian sid. This bug freezes everything and I have to do a hard reboot. It happens with flashplugin and pepperflash when I play a video with flash (both tested with firefox and chromium). Today I am using pepperflash, installed by the package browser-plugin-freshplayer-pepperflash. The bug could occur after playing 2s or 2h. When I play a flash video, I have ~50% chances to be affected.
Have you tried switching to a VT and back when this happens? There was a bug in... I *think* it was something like opengl ... recently, whereby a bunch of unrelated programs (chrome/chromium included) could freeze the display. Switching away from X and back caused the display to refresh and things would work again (for a time).
I have some difficulties to see where it comes from. I need some help. Here is the /var/log/debug for the time of the bug (occurred today at 21:25) : https://hastebin.com/hupeqituji.sql In /var/log/daemon.log I have some inconsistencies at 21:25:28 represented by: ^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@...
This is less's representation of null characters and is an artefact of journaling file systems. Syslog has told the file system "I'm about to write X bytes to /var/log/daemon.log" and then, at some point during the writing of that, you've killed the power. During either fsck or mount (depending on the file system), the journal is replayed - that is, there is a log saying "X bytes were being writen to /var/log/daemon.log". Now, most of those bytes never made it to the disk, but the record is still there. So the file grows by X bytes of nothing. Now the file system is consistent (the metadate, at least, the idea being that it's better to have SOME of the file still there, rather than a broken filesystem)
