Hi, list As the subject, here is the related log: [72873.713472] Call Trace: [72873.713473] <IRQ> [72873.713474] switch_mm_irqs_off+0x31b/0x4e0 [72873.713475] xnarch_switch_to+0x2f/0x80 [72873.713476] ___xnsched_run.part.74+0x154/0x480 [72873.713476] ___xnsched_run+0x35/0x50 [72873.713477] xnintr_irq_handler+0x346/0x4c0 [72873.713478] ? xnintr_core_clock_handler+0x1b6/0x360 [72873.713479] dispatch_irq_head+0x8e/0x110 [72873.713479] ? xnintr_irq_handler+0x5/0x4c0 [72873.713481] ? dispatch_irq_head+0x8e/0x110 [72873.713482] __ipipe_dispatch_irq+0xd9/0x1c0 [72873.713483] __ipipe_handle_irq+0x86/0x1e0 [72873.713483] common_interrupt+0xf/0x2c [72873.713484] </IRQ> Maybe, the later one(i.e. </IRQ>) implies there was an interrupt request and the common_interuppt() function handler it. Am I right? But what about the former one(i.e. <IRQ>)?
