This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

The problem seems to be related to an add-on PCI-E SATA card: 22:00.0 SATA controller: ASMedia Technology Inc. ASM1062 Serial ATA Controller (rev 02) When disks are connected to the card port -> panic, no disks connected -> no panic.
