Subject: Re: radeon ARUBA NULL pointer dereference

Follow-up, qla2xxx appears to be fixed, most recent test was with:

commit 684a64bf32b6e488004e0ad7f0d7e922798f65b6 (HEAD -> master,
origin/master, origin/HEAD)
Merge: f7fccaa77271 68898131d2df
Author: Linus Torvalds <torvalds@...ux-foundation.org>
Date:   Tue Sep 24 15:44:18 2024 -0700

    Merge tag 'nfs-for-6.12-1' of
git://git.linux-nfs.org/projects/anna/linux-nfs

I suppose the most likely fix was probably this one but I do not have
the HW to verify
(report I got was on an AMD EPYC 7262):

commit b348b6d17fd1d5d89b86db602f02bea54a754bd8
