[SOLVED] Rpi3 - kworker blocked for more than 120 seconds

Several months back I purchased a Raspberry Pi 3. Naturally I installed Slackware ARM -current to take advantage of hard float. I used the image from Dec 12 2016, sarpi3-installer_slackcurrent_fd0.img.xz. I have been very busy since then and never got around to using it. Today I decided to replace my old wireless router with the Rpi3. I updated the system packages to the latest -current. I also updated the kernel to 4.9.19-v7 using the rpi-update command.

Upon running sbopkg -r I noticed rsync timed out with an error:

rsync error: timeout in data send/receive (code 30) at io.c(137) [sender=3.0.8]

In /var/log/syslog the following error is saved:

I realize this is related to the sd card but was unable to find any answers after googling for a bit.

Does anyone have some ideas as to what is causing this?

I am going to make this as resolved since I haven't seen any further messages after having done many cpu and disk intensive tasks.

task system sleep: 12660 blocked for more than 120 seconds in centos 7 error is coming then automatically my website down.

Unless I had the exact same card and could match the conditions under which you've experienced this error I'd be hard pressed to replicate the issue and/or find any answers.
