Hi,

Yeah I also checked the kernel logs and saw kernel panic logs. I will
attach the kernel logs on this email. Another fact I saw, was that today (Monday, the first day of the week) the fstream systemd timer is started
and during the operation on the RAID device, the system load grows and
stuck up and the same kernel panic happened. Similar to formatting the filesystem with discard enabled.
I will examine the scenario with the kernel version that Theodore has mentioned and will update it here.
