Hi Hillf,
I don't know if it's a good fix on its own or not,
but arm64 command line parsing is currently broken and does not allows
us to increase stall timeouts:
https://groups.google.com/g/syzkaller-bugs/c/QoFsDszFLxY/m/mnnUTKuJAAAJ
This may lead to some false stall reports (the timeout is 22s, but we
set it to 300s on syzbot).
