| Series | [PASEMI] Nemo board doesn't reboot anymore after the commit "HID: usbhid: Add ALWAYS_POLL quirk for some mice" | expand |
[Note: this mail contains only information for Linux kernel regression tracking. Mails like these contain '#forregzbot' in the subject to make then easy to spot and filter out. The author also tried to remove most or all individuals from the list of recipients to spare them the hassle.] On 22.12.22 11:42, Christian Zigotzky wrote: > > The Nemo board [1] doesn't reboot anymore since the final kernel 6.1. > The reboot works with the RC8 of kernel 6.1. > Actually, a reboot works but the CFE firmware is not loaded.

To be sure below issue doesn't fall through the cracks unnoticed, I'm adding it to regzbot, my Linux kernel regression tracking bot: #regzbot ^introduced f6d910a89a23 #regzbot title hid: PASEMI Nemo board doesn't reboot anymore #regzbot ignore-activity Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) P.S.: As the Linux kernel's regression tracker I deal with a lot of reports and sometimes miss something important when writing mails like this. If that's the case here, don't hesitate to tell me in a public reply, it's in everyone's interest to set the public record straight.
Hello, The reboot issue is still present in the RC2 of kernel 6.2. We still need the usbhid.patch. [1] Please check the bad commit.

[2] Ankit, have you tested with all the devices that you added the quirk for in your original patch? Unless I hear otherwise, I will just drop the quirk for USB_DEVICE_ID_CHERRY_MOUSE_000C before this gets clarified. Thanks,

Given the lack of input from Ankit, I have just queued the patch below in for-6.2/upstream-fixes. From: Jiri Kosina <jkosina@suse.cz> Subject: [PATCH] HID: revert CHERRY_MOUSE_000C quirk This partially reverts commit f6d910a89a2391 ("HID: usbhid: Add ALWAYS_POLL quirk for some mice"), as it turns out to break reboot on some platforms for reason yet to be understood.

Hello, The Nemo board [1] doesn't reboot anymore since the final kernel 6.1. The reboot works with the RC8 of kernel 6.1. Actually, a reboot works but the CFE firmware is not loaded. Maybe there is still something in the memory after the reboot. I bisected today. [2] The commit "HID: usbhid: Add ALWAYS_POLL quirk for some mice". [3] is the problem. I was able to revert this commit and the reboot works without any problems again. I created a patch for reverting the bad commit. [4] Then compiled the kernel with this patch. After that, the X1000 reboots without any problems. I use a Cherry USB mouse. [5] Please check the bad commit.
