You didn't say what operating system you are running or what nut version. However, based on: > [21963.079554] > ================================================================== > [21963.079580] BUG: KFENCE: memory corruption in free_async+0x1d8/0x1e0 > [21963.079580] > [21963.079604] Corrupted memory at 0x0000000025448a9e [ ! ! ! . . . . . . . > . . . . . . ] (in kfence-#183): > [21963.079711] free_async+0x1d8/0x1e0 > [21963.079728] usbdev_ioctl+0x138/0x1c40 > [21963.079744] __arm64_sys_ioctl+0xd0/0x130 > [21963.079769] invoke_syscall+0x7c/0x130 > [21963.079793] el0_svc_common.constprop.0+0x6c/0x160 > [21963.079815] do_el0_svc+0x38/0x120 > [21963.079835] el0_svc+0x34/0xc0 > [21963.079856] el0t_64_sync_handler+0x11c/0x150 > [21963.079876] el0t_64_sync+0x198/0x19c it looks like this is a kernel memory validator of some kind, and it is objecting to memory handling within the kernel. I would therefore guess this is not a nut or device bug, and would suggest reading the usbdev_ioctl proc_do_submiturb source code. Guessing wildly, there might be an out-of-bounds write. _______________________________________________ Nut-upsuser mailing list [email protected] https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/nut-upsuser
