Hello, I was trying out today's linux-next-20200304 and noticed this splat in KMSG: [ 1.161244] BUG: sleeping function called from invalid context at drivers/base/power/runtime.c:1075 [ 1.161393] in_atomic(): 1, irqs_disabled(): 128, non_block: 0, pid: 37, name: kworker/u8:1 [ 1.161481] CPU: 1 PID: 37 Comm: kworker/u8:1 Not tainted 5.6.0-rc4-next-20200304-00181-gbebfd2a5be98 #1588 [ 1.161616] Hardware name: NVIDIA Tegra SoC (Flattened Device Tree) [ 1.161769] Workqueue: ci_otg ci_otg_work [ 1.161882] [<c010e8bd>] (unwind_backtrace) from [<c010a315>] (show_stack+0x11/0x14) [ 1.162035] [<c010a315>] (show_stack) from [<c0987d29>] (dump_stack+0x85/0x94) [ 1.162132] [<c0987d29>] (dump_stack) from [<c013e77f>] (___might_sleep+0xeb/0x118) [ 1.162281] [<c013e77f>] (___might_sleep) from [<c052fa1d>] (__pm_runtime_resume+0x75/0x78) [ 1.162427] [<c052fa1d>] (__pm_runtime_resume) from [<c0627a33>] (ci_udc_pullup+0x23/0x74) [ 1.162575] [<c0627a33>] (ci_udc_pullup) from [<c062fb93>] (usb_gadget_connect+0x2b/0xcc) [ 1.162665] [<c062fb93>] (usb_gadget_connect) from [<c062769d>] (ci_hdrc_gadget_connect+0x59/0x104) [ 1.162807] [<c062769d>] (ci_hdrc_gadget_connect) from [<c062778b>] (ci_udc_vbus_session+0x43/0x48) [ 1.162949] [<c062778b>] (ci_udc_vbus_session) from [<c062f997>] (usb_gadget_vbus_connect+0x17/0x9c) [ 1.163089] [<c062f997>] (usb_gadget_vbus_connect) from [<c062634d>] (ci_otg_work+0xbd/0x128) [ 1.163245] [<c062634d>] (ci_otg_work) from [<c0134719>] (process_one_work+0x149/0x404) [ 1.163335] [<c0134719>] (process_one_work) from [<c0134acb>] (worker_thread+0xf7/0x3bc) [ 1.163479] [<c0134acb>] (worker_thread) from [<c0139433>] (kthread+0xf3/0x118) [ 1.163621] [<c0139433>] (kthread) from [<c01010bd>] (ret_from_fork+0x11/0x34) I haven't tried to figure out what change causes this problem, it didn't happen using next-20200218.
