            Bug ID: 214311
           Summary: megaraid_sas - no disks detected
           Product: IO/Storage
           Version: 2.5
    Kernel Version: 5.10.0
          Hardware: Intel
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: blocking
          Priority: P1
         Component: SCSI
          Assignee: linux-scsi@vger.kernel.org
          Reporter: jarek@poczta.srv.pl
        Regression: No

Dell R340 with PERC H330 - disks not detected.

lspci:

02:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS-3 3008
[Fury] (rev 02)

dmesg:

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.

Salvatore
