linux-grsec 4.3.3.201512162141-1
Happens on VM as well as baremetal. Appears to be XFS specific. XFS is the root filesystem. xfs-repair does not find any problems on the file system.

This is the layout of the disk (for the VM):
Model: Virtio Block Device (virtblk)
Disk /dev/vda: 4295MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:

Number Start End Size File system Name Flags
1 17.4kB 4194kB 4177kB bios_grub
2 4194kB 4295MB 4291MB xfs msftdata


From the trace, it seems this is something systemd is trying to do, like mkdir or so. Might be tied to systemd journal, since I've sometimes seen it blow up in the journal phase.

Upgrade to 4.3.3.201512222129-1 and let me know if it's still an issue.

Hello, thanks for the reply. I did a quick check with 4.3.3.201512282134-1-grsec and it seems to boot up normally. Is this by chance or is there a bugfix in this version?

There were various fixes for both upstream bugs and false positives from the overflow checking plugin.
