            Bug ID: 214311
           Summary: megaraid_sas - no disks detected
           Product: IO/Storage

            Status: NEW

Dell R340 with PERC H330 - disks not detected.

lspci:

This machine works OK with kernel 4.19.0. Debian 11, Clonezilla 2.7.3-19 does
not detect disks.

This sounds very similar to one bug report which was reported
downstream in Debian at https://bugs.debian.org/992304

Followup to the bugzilla bug 214311
(https://bugzilla.kernel.org/show_bug.cgi?id=214311) suggests that it
works when booting with BIOS, not with UEFI boot.
