Until recently on my armv7h devices, I was recently had been using for a while the linux-libre-vanilla kernel, which worked without issue.

After the recent updates to both the linux-libre and linux-libre-lts kernel I did a usual upgrade of pacman -Syu and updated all fine (though due to another know bug had to copy the vmlinuz for those two kernels). I started with the lts kernel and after within a day I got the following, (please note this is for the linux-libre kernel, but I was getting the same for the lts (which prompted me to switch to the linux-libre kernel to see if was a bug in that kernel or elsewhere.

Feb 22 06:55:10 myhostname kernel: INFO: task syncthing:1827 blocked for more than 120 seconds.
Feb 22 06:55:10 myhostname kernel: Tainted: G WC 6.6.8-gnu-1 #1
Feb 22 06:55:10 myhostname kernel: "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

After which follows a exceptions etc, it did this several times and stops. I thought it might have been a hardware issue until it started doing it on my other armv7h device (a cubieboard) with a newer and bigger drive and to which isn't running syncthing (as i thought it was a bug there) and which had similar timeouts/blocks/hangs for postfix/kworker and systemd.

As a last attempt, I switched back to the linux-libre-vanilla kernel (on both devices) that I had been using before have given it some days to see if the problem reoccurred, it doesn't. Which leads me to reporting this to issue as it may involve the linux-libre and linux-libre-lts kernels or the way in which the interact with something else.

Hope this makes sense
