[linux-aarch64] upgrade to 6.12.10 : no usb device show up

[lafleur]

Upgrading to linux-aarch64-6.12.10-1, the USB disks on my device fail to show up. Downgrading to linux-aarch64-6.12.1-2 works the issue around.

I'm running plain archlinuxarm on a Nanopi R5C.

I may provide more details, but will not be able to test the new kernel for the next few weeks.

Probably want to open a report with upstream:make_clickable_callback(MAGIC_URL_FULL, ' ', 'https://github.com/raspberrypi/linux/issues', '', ' class="postlink"')

@graysky : are you positive I should report to `https://github.com/raspberrypi/linux/issues` ? I'm running a plain `linux-aarch64` kernel on a NanoPi r5c, so to me it's very remotely related to Raspberry Pi.

[graysky]

My bad, I thought I read that you were running the rpi kernel not the aarch64 kernel. I see no config changes between the two kernels you called out so the change is likely in the kernel code itself. linux-aarch64 got bumped to 6.13.0 does that work?

I can confirm a similar issue on cubietruck (armv7): linux-armv7-6.12.1-2 works, linux-armv7-6.13-2 does not (lsusb output is empty).

[lafleur]

@graysky : kernel 6.13.0-2 didn't fix the issue - still no USB drives detected.

[graysky]

Although not in the repo, 6.13.5 is the latest. Can you build it and try? Failing some upstream change, we will need to understand if there is a missing module for this device.

Can you boot into the kernel that works and post the output of lsmod

[wobble]

FWIW, works again for me with linux-armv7-6.14.6-1-armv7h (can't say anything about aarch64!).

Comparing lsmod output of 6.13 and 6.14.6 I can't spot anything interesting, it's just that the usb-related modules are missing on 6.13 (like usbserial).

There is a difference in dmesg, this whole part is missing on 6.13:
