[lubuntu-devel] bug #1763611, Lubuntu bionic boots slower than the other Ubuntu flavours with some SSDs

[Nio Wiklund]

Hi Volker,

I think this indicates (contrary to the findings reported at the Ubuntu 
Forum thread) that the problem is not the size of the physical sector 
size, but something else (maybe still connected to SSDs).

Or maybe the problem (bug) is different for you and me.

Best regards
Nio
