Title:
  Kernel cannot detect the full memory

Status in linux-signed-hwe-6.2 package in Ubuntu:
  New

Bug description:
  Hi ubuntu,
  I use ubuntu22.04 in my laptop. When I open the laptop, sometimes ubuntu 
cannot detect all memory.
  My laptop has 16GB memory, sometimes ubuntu detect 2.5GB. 

  I already use memtest86 test the health of the memory. It doesn’t show any 
error.
  I think this problem is from the OS. Please help me!

  
  Thank you very much
  Ray
