Remember that the patch I wrote is only intended to fix the crash (bug
2).  The probe failure of aacraid (bug 1) is still a mystery.

The Debian Kernel Handbook
<https://kernel-team.pages.debian.net/kernel-handbook/> is an official
guide maintained by the Debian kernel team (mostly me), and I would
recommend that over the blog you found.

The problem with test-patches that I mentioned earlier has been fixed.

The crash bug was introduced way back in Linux 2.6.15, which is why my
fix was applied to all supported versions.

Ben's patch to fix the crash bug was applied in 6.11-rc6 and down the
road to various stable series (in particular it is in v6.10.8 and
6.1.108).

Do you still see Bug #1? 

I'm closing the bug but please do  reopen the bug and rmeoving the
moreinfo tag if you still encounter the issue. In this case you please
attach updated information, fresh bootlogs?

Regards,
Salvatore
