Comment 214 for bug 1746340

I have a Dell Inspiron 14 5000 Series-5480. The most strange thing is that I bought my laptop about 1 year ago and I've installed Ubuntu 18.04.1 with kernel 4.15.0-65-xxx (default installation) and everything worked as expected. However, the same problem happened with any other kernel version (including 4.17.0-041700-generic).

Then, after having some problems with my system I've installed Ubuntu 18.04.4. The kernel version installed with the system was 5.3 and after observing the same problem with the disk I've tried to install 4.15.0-65 and the problem has not been solved (I don't remember exactly which kernel version I had in the first time (e.g. what was the xxx)). Finally, I've found that 4.17.0-041700-generic works and I don't know why. It didn't work with Ubuntu 18.04.1 and it works with 18.04.4. This is really strange and I need to use most recent kernel versions, because I need to use some features I've implemented for v5.5-rc1.
