Bug#1076555: linux-image-6.9.9-amd64: boot crash RIP: 0010:kmem_cache_alloc

[Patrice Duroux <patrice.duroux@gmail.com>]

Hi Ben,

All my attempts both after installing 6.9.9 on my current Sid system,
or using a snapshot of Sid at that time when linux-image-6.9.9 was pushed
(fastidious by the way) have failed. I am not able to get the issue again.

But since then it occurs to me that there was also a firmware update (fwupd)
for my Dell laptop system (1.32.0 to 1.34.0)
