Public bug reported: Commit 5467801f1fcb ("gpio: Restrict usage of GPIO chip irq members before initialization") attempted to fix a race condition that lead to a NULL pointer, but in the process caused a regression for _AEI/_EVT declared GPIOs.
This manifests in messages showing deferred probing while trying to allocate IRQs like so: amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x0000 to IRQ, err -517 amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x002C to IRQ, err -517 amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x003D to IRQ, err -517 [ .. more of the same .. ] The code for walking _AEI doesn't handle deferred probing and so this leads to non-functional GPIO interrupts. ** Affects: linux (Ubuntu) Importance: Undecided Status: Incomplete ** Affects: linux-oem-5.14 (Ubuntu) Importance: Undecided Status: New ** Affects: linux-oem-5.17 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1971597 Title: amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x0000 to IRQ, err -517 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1971597/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
