Hi all Since years I have had rtirq perfectly working on my Devuan/Debian DAW (sysV init). Now with Devuan3/Debian10, after booting the RT priority are not set. Only after restarting rtirq, priority are as expected (see below). The rtirq service was started during boot, but without setting priorities. I cannot explain why. Any ideas? Thans in advance Regards ~~~ $ sudo /etc/init.d/rtirq status PID CLS RTPRIO NI PRI %CPU STAT COMMAND 57 FF 50 - 90 0.0 S irq/9-acpi 79 FF 50 - 90 0.0 S irq/12-i8042 80 FF 50 - 90 0.0 S irq/1-i8042 81 FF 50 - 90 0.0 S irq/8-rtc0 129 FF 50 - 90 0.0 S irq/17-ehci_hcd 174 FF 50 - 90 0.0 S irq/27-xhci_hcd ... 411 FF 50 - 90 0.0 S irq/18-ohci_hcd 865 FF 50 - 90 0.0 S irq/20-snd_ice1 905 FF 50 - 90 0.0 S irq/37-radeon 1995 FF 50 - 90 0.1 S irq/22-eth0 3 TS - 0 19 0.1 S ksoftirqd/0 23 TS - 0 19 0.1 S ksoftirqd/1 32 TS - 0 19 0.1 S ksoftirqd/2 41 TS - 0 19 0.1 S ksoftirqd/3 $ sudo /etc/init.d/rtirq restart Setting IRQ priorities: stop [rtc0] irq=8 pid=81: OK.
