Public bug reported:
I have a brand new Dell Laptop with an Adata SSD. I've installed Ubuntu 18.04
and it seemed to work fine, but then I noticed that the root filesystem got
corrupted more than once while in normal use.
Upon investigation, I've found that this seems to happen only when working on
battery (that's why I took a while to notice the problem). When on AC,
everything seems to be fine.
I've tried booting with a newer and an older kernel to see if the
problem is solved. It looks like 4.15.0-72 has the same problem, while
5.4.2 (got this fromm mainline) works fine.
This is what appears on dmesg after unplugging AC while doing IO:
