https://bugzilla.kernel.org/show_bug.cgi?id=215799 Bug ID: 215799 Summary: apple-mfi-fastcharge causes automatic pm hibernation entry, when iPhone gets attached Product: Drivers Version: 2.5 Kernel Version: 5.17.1 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: USB Assignee: drivers_usb@xxxxxxxxxxxxxxxxxxxxxx Reporter: labre@xxxxxxxxx Regression: No Created attachment 300695 --> https://bugzilla.kernel.org/attachment.cgi?id=300695&action=edit dmesg log during a boot with an iPhone attached ======================= Summary ======================= If I attach an iPhone SE while the apple-mfi-fastcharge module is not blacklisted, the kernel will immediately hibernate. Loading the module without an attached iPhone does not have this effect. dmesg is not very helpful in this case, probably I need a higher debug level. I’ll attach it anyway with some context. ======================= Steps to reproduce ======================= 1. Attach an iPhone SE (don’t have any others) via USB-A to Lightning cable while apple-mfi-fastcharge is either builtin, loaded, or can be loaded automatically, i.e. is not blacklisted. ======================= Actual behaviour ======================= The kernel automatically hibernates without user interaction. ======================= Expected behaviour ======================= The kernel continues normal operation. ======================= Additional information ======================= The cable has μUSB→Lightning and μUSB→USB C adapters attached. It works fine with an Android phone and with the iPhone SE without the apple-mfi-fastcharge module loaded, so it is not faulty. -- You may reply to this email to add a comment.
