OK, so we have:

> WARNING: CPU: 11 PID: 541 at mm/page_alloc.c:4556 __alloc_pages+0x2a3/0x340

This means something tried to allocate a chunk of kernel memory that is
larger than the kernel page allocator supports.

That happened during initialisation of the dell_wmi_sysman module.

Then later on the kernel heap allocation crashes, suggesting memory
corruption.  Maybe related to the first failure, maybe not.

- There is a newer kernel version available in unstable now (6.10.6 or
maybe 6.10.7 by the time you read this).  Does that fix the issue?

- Do these same error messages appear on every boot?

- If you prevent the dell_wmi_sysman module loading, by adding
"blacklist=dell_wmi_sysman" to the kernel command line, do all of the
error messages stop appearing?
