Got this panic after booting GENERIC kernel: panic: malloc(M_WAITOK) with sleeping prohibited cpuid = 3 time = 1643658859 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe00c7b20ae0 vpanic() at vpanic+0x17f/frame 0xfffffe00c7b20b30 panic() at panic+0x43/frame 0xfffffe00c7b20b90 malloc_dbg() at malloc_dbg+0xd4/frame 0xfffffe00c7b20bb0 malloc_domainset() at malloc_domainset+0x36/frame 0xfffffe00c7b20c20 bounce_bus_dmamem_alloc() at bounce_bus_dmamem_alloc+0x5b/frame 0xfffffe00c7b20c50 os_dma_mem_alloc() at os_dma_mem_alloc+0xe3/frame 0xfffffe00c7b20c90 pqisrc_build_send_raid_request() at pqisrc_build_send_raid_request+0x78/frame 0xfffffe00c7b20d30 pqisrc_write_current_time_to_host_wellness() at pqisrc_write_current_time_to_host_wellness+0xff/frame 0xfffffe00c7b20df0os_wellness_periodic() at os_wellness_periodic+0x1a/frame 0xfffffe00c7b20e10 softclock_call_cc() at softclock_call_cc+0x14d/frame 0xfffffe00c7b20ec0 softclock_thread() at softclock_thread+0xc6/frame 0xfffffe00c7b20ef0 fork_exit() at fork_exit+0x80/frame 0xfffffe00c7b20f30 fork_trampoline() at fork_trampoline+0xe/frame 0xfffffe00c7b20f30 The reason seems to be obvious enough, changing BUS_DMA_WAITOK to BUS_DMA_NOWAIT in os_dma_mem_alloc() helps.
