Opened by olo31. Modified

Close Issue

Since Kernel Linux 6.11.0-400.asahi.fc40.aarch64+16k, changing IO Scheduler from default (mq-deadline) to "none" (for example) is broken.

> cat /sys/block/*/queue/scheduler
none [mq-deadline] kyber bfq 
none [mq-deadline] kyber bfq 
none [mq-deadline] kyber bfq 
> echo none | sudo tee /sys/block/nvme0n1/queue/scheduler
none
tee: ../src/iopoll.c :230 : fwrite_wait:  l'assertion « size >= 0 » a échoué.
> cat /sys/block/*/queue/scheduler
none [mq-deadline] kyber bfq 
none [mq-deadline] kyber bfq 
none [mq-deadline] kyber bfq

No problem with kernel Linux 6.10.9-403.asahi.fc40.aarch64+16k.

> cat /sys/block/*/queue/scheduler
  [none] mq-deadline kyber bfq 
  [none] mq-deadline kyber bfq 
  [none] mq-deadline kyber bfq

Tested on a MacbookPro M2Pro 16".
