IIRC when I hooked up a monitor, I didn't see any kernel oops, just back to u-boot. https://bugzilla.redhat.com/show_bug.cgi?id=2264560 It's very weird, and I'm just speculating that the 20-30 seconds is about how long it takes for the GPS HAT to start sending PPS pulses. I need to swap out the SD card for a clean Fedora 41 server image and see if it still happens (I expect it will since kernel 6.11 on F39 still does). I was kind of hoping I could reproduce it with the other GPS HAT, but it doesn't happen there. That's when I thought about the difference between the two being which GPIO PIN the PPS signal is on (think I had it backwards before - the one that crashes has PPS on the default pin, 18, while the one that doesn't has PPS on GPIO pin 4). It doesn't make much sense for the GPIO PPS signal to be the issue (even when the overlay configuring PPS isn't loaded), but... not sure what else it might be. The only other difference between the two HATs is that the one on the crashing Pi has an integrated RTC, while the other one does not. -- Chris Adams <linux@xxxxxxxxxxx> -- _______________________________________________ arm mailing list -- arm@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to arm-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/arm@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
