Comment 4 for bug 1769433

After finishing the installation, I wasn't able to start the OS again (forever waiting with a black screen). The first thing I saw while looking for answers was that 32-bit wasn't supported, assumed that that was problem and reinstalled it again. In any case and as said, the installer didn't recognise the partition as a valid OS (either 64 bit was installed or something went completely wrong) and forced a formatting.

Regarding messing everything up, it might be caused by a different issue: an old Linux Kernel. Note that I use that computer under quite tough CPU/IO conditions (lots of reading/writing to a database) and that it is quite old. The last time I installed everything from scratch the load was much lower and these weird issues (e.g., getting regularly frozen and having to manually fsck at startup over and over) didn't happen, so I assumed that it was some of the files/modifications from the faulty 64-bit installation. But apparently it was some kind of bug which is fixed in the last stable Kernel. BTW, I relied on both MySQL and MariaDB and the later seems to manage the situation more gracefully (unnecessarily slow, but not showing the aforementioned behaviours).
