Make sure to never assign a time slice longer than the default time slice, that can be used as an upper limit.
This seems to prevent potential stall conditions (reported by the CachyOS community) when running CPU-intensive workloads, such as:
[ 68.062813] sched_ext: BPF scheduler "rustland" errored, disabling [ 68.062831] sched_ext: runnable task stall (ollama_llama_se[3312] failed to run for 5.180s) [ 68.062832] scx_watchdog_workfn+0x154/0x1e0 [ 68.062837] process_one_work+0x18e/0x350 [ 68.062839] worker_thread+0x2fa/0x490 [ 68.062841] kthread+0xd2/0x100 [ 68.062842] ret_from_fork+0x34/0x50 [ 68.062844] ret_from_fork_asm+0x1a/0x30
