Hi,

I have upgraded the kernel from 4.19.97 to 5.4.28 on my server. After reboot, I got the kernel panic.
The kernel listed the two logical drives installed in the server. The first logical drive, where lies the EFI partition, primary partition with the root and user home and swap partition, was showing only the EFI partition.
The second logical drive where NAS stuff lies, showed the only partition which is set, correctly.

I did a reboot (by pressing the power button for over 5s, as the panic blocked the system). After the reboot, the system booted fine.
I since then have not rebooted the system and seems to work fine.

My question: Should I be concerned? Is this a one time glitch or should I reboot the system multiple times to check?

Thanks for your educated guess :D

BR

Hardware RAID creates a logical drive out of two 300GB SAS disks (raid 0) and 3TB out of 4 1TB SAS disks (raid 4).
On the 300GB drives, I have Gentoo and user homes
On the 3TB lies the shared stuff.
