FS#1773 - dwc2 on Arcadyan ARV752DPW - The router restarts after inserting the modem E3372h to the usb port #6746
Comments
mkresin: Unfortunately release image have the debug information stripped, which make the stack trace not that useful. Would it be possible that you try a master/snapshot image or build an 18.06 image with the following options set:
CONFIG_KERNEL_KALLSYMS=y
CONFIG_COLLECT_KERNEL_DEBUG=y
|
zuzia: Thank you for your comments. Following your advice, I get a new crash log with OpenWrt 18.06-SNAPSHOT, r7254-75e4d2d18c:
|
mkresin: Dammed, you're already using kernel 4.9.119 which includes [[https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-4.9.y&id=7ff1861f49e64da20a9b9451ebbdc9bbf68b8a4b|7ff1861f49e64da20a9b9451ebbdc9bbf68b8a4b]]. I would have though this one fixes your issue. It might be that the issue is fixed in master with kernel 4.14. There were quite some usb changes in lantiq with the switch to kernel 4.14. Beside of that, I've no idea what the reason for the crash could be. |
zuzia: Module dwc2 on kernel 4.14 (SNAPSHOT, r7847-03e5dcbf10) doesn't work - cannot be initialized:
|
zuzia: Same behaviour with latest snapshot r7865-d74d6c4, USB not working.
|
mkresin: Yeah, totally forgot about the error. It's already reported as FS#1634. Someone needs to check at which point the EPROBE_DEFER is returned. Near to impossible to do it without access to the hardware. |
