Why are hibernation failures more common in this class of device than
anything else? The hibernation flow is nearly all done in Linux driver
code (with the exception of ACPI calls that move devices into D3 and out
of D0).
Perhaps you're seeing a manifestation of a general issue that we're
working on a solution for here:
https://lore.kernel.org/linux-pm/20251025050812.421905-1-safinaskar@gmail.com/
https://lore.kernel.org/linux-pm/20251026033115.436448-1-superm1@kernel.org/
https://lore.kernel.org/linux-pm/5935682.DvuYhMxLoT@rafael.j.wysocki/T/#u
Or if you're on an older kernel and using hybrid sleep we had a generic
issue there as well which was fixed in 6.18-rc1.
Nonetheless; don't make policy decisions based upon kernel bugs. Fix
the kernel bugs.
