[-- Attachment #1 --] During a large build (llvm13), my system ground to a near halt with almost everything suspended. After several minutes, the system slowly recovered. When I looked at the messages log, I found 57 kernel messages spread over 3.75 hours, in the form of: wap_pager: indefinite wait buffer: bufobj: 0, blkno: 862845, size: 20480 The block numbers and sizes varied. bufobj was always '0'. I had significant swap available swap space,as far as I could tell. I have 20GB of RAM and 24GB of swap. I am running stable 48937-3c6b6246f2f from January 13. I know that the LLVM build is huge, but I've not seen this before. What, exactly, is this message telling me? Am I out of RAM and swap? I couldd add another 24GB of swap, though it would be on spinning rust, not SSD.
