So you should probably start first with running latest available kernel - 4.19.

You also should collect 'dmesg' report

I've already the last Debian kernel (4.18.20). Kernel 4.19 is not packaged yet.
In #913119 there was a complete dmesg, that I've also attached here.

Aren't you running out-of-memory ?

Not that I'm aware of. In the top bar I have an applet that shows cpu, ram
and swap usage and I've never noticed too high ram usage. I'll pay more
attention to that the next time I'll make a test.

I've not noticed any corruption due to these freeze but often they are very
long and very impacting. The only reliable workaround found was to reboot with:
scsi_mod.use_blk_mq=0 dm_mod.use_blk_mq=0

I doubt this have anything in common with this.

That's surprising to me. I assure you that, until now, it's the only
thing that really resolved for me and that let me use Debian kernels
from 4.17 to 4.18.
I look forward to test 4.19 as soon as it will be available.
