Description:

Sometimes (3 out of 10 times) when I build AOSP image inside a docker container my pc hangs
the mouse is not moving, music stops, and keyboard not responding (numlock doesn't work).

Only happens on kernel versions 4.18 and 4.19. LTS 4.14 works fine, and i don't remember having this issue on 3.17 and earlier.

When I saw "kswapd" in the log, I thought maybe my SSD goes bad, so I moved the swap partition from SSD to the regular hard drive,
but this didn't help, in fact the hangs started happening more frequently.

Happened again today on 4.20.3 kernel. Versions "4.19.4" and "4.20.1" were quiet, I didn't see any hangs while using them, and I almost thought the issue was resolved.

I cannot reproduce the issue. Is it still valid for you?
