Hello -
I am seeing this fault when i plugin a external usb device, and was
wondering if this indicates DMA/Cache coherency problem
-----
_ehci_append_qh: 0xf3dd2300 to 0xf3dc3c00
Kernel page fault with the following non-sleepable locks held:
exclusive sleep mutex ehci0 (usb_def_mtx) r = 0 (0xc73ece74) locked @
sys/dev/usb/usb_transfer.c
exclusive sleep mutex USB device mutex (USB device mutex) r = 0 (0xc73da850)
locked @ /sys/dev/usb/usb_transfer.c
Stopped at usb_pc_cpu_flush+0xc: ldr r2, [r0, #0x018]
----------------------------
Thanks
kott
