OK, I somehow managed to miss it as it had different naming convention sorry.

Anywhow, I see this:

RSI=0x0c, which maps to the parameter 'order' in __alloc_pages_noprof(), which
allocates 
4096*2**0xc = 16777216 = 16 MiB of memory. This means that memory consumed by
the log is in the range 8 MiB < N <= 16 MiB.

It's a huge buffer to bind. Are you sure that there is no BIOS bug and what is
the exact target hardware, BIOS type and version etc. Have you reported to the
vendor? This definitely is not normal.

And I don't understand where Stefan got his size figures, which are completely
different...
