Hello, syzbot found the following crash on: HEAD commit: 983542434e6b Merge tag 'edac_fix_for_5.0' of git://git.ker.. git tree: upstream console output:https://syzkaller.appspot.com/x/log.txt?x=17476498c00000 kernel config:https://syzkaller.appspot.com/x/.config?x=505743eba4e4f68 dashboard link:https://syzkaller.appspot.com/bug?extid=40e28a8bd59d10ed0c42 compiler: gcc (GCC) 9.0.0 20181231 (experimental) Unfortunately, I don't have any reproducer for this crash yet.Hmm nothing obvious below. Generic corruption elsewhere?Hard to say, a silent memory corruption is definitely possible. If there is nothing obvious let's wait, maybe syzbot will come up with a repro or we get more such hangs so that it will be possible to rule out flakes/corruptions.
It hasn't been reproduced for a while. We can invalid this and see if we can get it again. So #syz invalid Thanks _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
