my Debian machine is a Fitlet2 with 64 GB SSD and an external Toshiba HDD.

this machine has been running flawlessly on Debian 9 - Stretch
but since an upgrade to Debian 10 - Buster, there are issues with the SSD becoming read-only
this appears in /var/log/syslog

what I have done so far is adding the following kernel parameter:

smartctl tells me this:

as an SSD might not work very well with SMART, I have done:

sudo smartctl disable smartd


my question is: what else can I do ??
going back to Stretch does not feel right, but what else is there ??

oh, really ??
currently it is a m.2 SSD - Kingspec NT-64 (2242) with 64 GB
the footprint of my Debian now is less than 5 GB, so I could go for 32 GB
any particular brand ??

When faced with problems like this I start experimenting. First, backup or transfer all important stuff.

dilberts_left_nut has a good suggestion but I'd modify it a bit. Can you scrounge up an old drive to experiment with? If so, load it with a pre-configured Debian 10; choose your preferred flavour such as XFce. Run that for long enough to see if the problem returns.

Did this problem exist immediately with the upgrade? How did you do the upgrade? My personalized Stretch does not like upgrading to Buster; I've tried several times but it always fails. However, when I install a pre-configured Buster it works. Consider a fresh install.

Is the problem intermittent?

Your 2018 hardware is too new to work out of the box with plain Stretch, though you can work around that with stretch-backports kernel, firmware, Mesa, etc.

But your drive's problems may not be related to Buster at all, and just might have decided to start going bad right at the same time, in which case you would have put in a lot of work for nothing.
The MX Linux repositories: Backports galore! If we don't have something, just ask and we'll try--we like challenges. New packages: Clipgrab 3.8.6, Hedgewars 1.0.0, PulseEffects 4.6.9, Telegram-desktop 1.8.15, Pale Moon 28.8.0, KeepassXC 2.5.1

I upgraded by modifying /etc/apt/sources.list, where I changed "stretch" into "buster".
next I ran "sudo apt update" followed by "sudo apt upgrade"
immediately after this upgrade my system hang itself and had to remove the power and connect it a while later.
checking the system as to what was running and what was new, I found "apparmor", which I removed.
this made my system stable again.
since than, it runs good and stable, until out of the blue, it hangs itself.
I can not do a reboot, and have to cycle the power.
this haning can happen after 2, 3 or 4 weeks.

that's what I experienced when I newly installed Stretch for the 1st time.
don't think I needed a stretch-backports kernel, but certainly had to add some firmware, etc.
and I got everything working :)

But your drive's problems may not be related to Buster at all, and just might have decided to start going bad right at the same time, in which case you would have put in a lot of work for nothing.

could very well be, as accidents will happen.
on the other hand, I am not the only one having exactly this problem.

Hopefully you did "apt full-upgrade" as well.

I might have done "sudo apt-get dist-upgrade" which is basically the same.
anyway, when I upgraded there were about 300 or 400 packages being updated/upgraded.

this morning sabnzbdplus made my machine almost unresposive.
all internal memory and also the complete swap was taken by sabnzbdplus.
this was eventually solved by stopping sabnzbdplus and removing its problamatic download.
all seems to be fine again.

looked in dmesg and syslog and found al lot of entries from ata1:
also many lines with "device reported invalid CHS sector 0"
this seems to be an old error.
never seen it before and also not after solving the memory attack of sabnzbdplus.

any suggestions ??

One probable cause is that your drive is dying. Back up everything important if you haven't already done so.

my data is on an external HDD
and I have a spare Raspberry 3B
so, I am pretty well covered :)
