Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
Images testing for SW RAID release 11.6

* What exactly did you do (or not do) that was effective (or
     ineffective)?
Installation testing option test matrix option #3 with the following
disk partitions

sda1 primary   1GB  B K raid (#1)
sda3 primary  15GB    K raid (#0)
sda5 logical   1GB    F swap  swap

RAID1 #0 jfs  /
RAID1 #1 ext2 /boot


* What was the outcome of this action?
kernel crash with 
[    2.671938] BUG: kernel NULL pointer dereference, address: 0000000000000028

(console output attached)


* What outcome did you expect instead?
Boot into fresh installed system :-)


* More details

(1) I have demonstrated this to Sledge on MULTIPLE instalations, both
BIOS and UEFI and various degraded RAID configurations.

(2) It appears to be Machine spacific; i.e. Sledge has been unable to
reproduce the problem on his hardware

(3) We have seen the problem on installations of debian 11.5 as well

(4) Occasionally I have been able to get lucky and the system has
booted.  This, coupled with #2 might suggest a race hazard / timing
issue?

Sorry

/Andy
