Hi, everyone, I strongly suspect something went wrong between Linux 5.6 and 5.7-rc1. This is an iBook G4 laptop with 1.5 GiB of RAM running the Debian powerpc port. I haven't bisected yet, since it's going to take quite a bit of time, so I'm sending this mostly as a heads-up (and to see if anybody has any clues about the possible cause). I'm using the following reproducer:
stress-ng --cpu 8 --io 8 --vm 8 --vm-bytes 1G --fork 8 --timeout 10m On Linux 5.7-rc1, this completely hangs the machine in about 30 seconds. Linux 5.6 survives the test. Let me know if I can provide any additional info, otherwise I'll just bite the bullet and start bisecting. Thanks, Rui
