Package: src:linux Version: 4.9.18-1~bpo8+1 Severity: normal Dear Maintainer,
the system is virtualized with kvm/libvirt under another debian jessie. Harddisks and network cards are provided by virtio. >From time to time but after some hours of uptime we get this kernel stacktrace. There is no special action needed to provike this. But i also see no influence on the system besides this output in the kernel log. Despite we are running a backport kernel i don't think it's specific to it. But if you like i could install a 3.16 and paste the output generated there. Thanks! -- Package-specific info: ** Version: Linux version 4.9.0-0.bpo.2-686 (debian-ker...@lists.debian.org) (gcc version 4.9.2 (Debian 4.9.2-10) ) #1 SMP Debian 4.9.18-1~bpo8+1 (2017-04-10) ** Command line: BOOT_IMAGE=/vmlinuz-4.9.0-0.bpo.2-686 root=UUID=1f561669-82f6-4b8a-b535-3bd027b9ccec ro console=ttyS0 ** Tainted: W (512) * Taint on warning. ** Kernel log: [ 5.301707] EXT4-fs: Warning: mounting with data=journal disables delayed allocation and O_DIRECT support!
