Interrupts An interrupt service routine (ISR) is a function that executes asynchronously in response to a hardware or software interrupt. 14 Introduction ¶ The ftrace infrastructure was originally created to attach callbacks to the beginning of functions in order to record and trace Hi, im using RHEL 8. 6. c and I find the problem is mcp251xfd_irq. The ‘probes’ are strictly typed functions that are passed a unique set of parameters defined by each tracepoint. After reboot it works for like a 5 minutes and Reproduction We've built a crash reproduction application that does nothing but allocate memory and append to log files.

McKenney This happens mainly because > > devm_request_threaded_irq already enables the ovp irq during probe. The “irq-flags tracing” feature “traces” hardirq and softirq state, in that it gives interested subsystems an opportunity to be notified of every hardirqs-off/hardirqs-on, softirqs-off/softirqs (1) handled = IRQ_NONE; (2) intf_pending = 0 (3) if (!(intf_pending)) return handled; handled = IRQ_NONE so this is the call trace reaseon. The spinlock is being held by another CPU that is just carrying out context switching.
