This should be fixed for the 5.2 release, as we now have a model of the cprman clock control module. ** Changed in: qemu Status: New => Fix Committed -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/

Thanks for the followup. Yes, that sounds like the problem is indeed that we don't currently emulate enough of the clock-control in the raspi's SoC. There were a couple of patches on list a while back that were trying to provide at least a basic dummy emulation of that device; I'm not sure what hap

This does not appear to be DIRECTLY a bug in QEMU, but 'something' has changed in the RPi Kernel to cause this issue. The actual cause of the panic is (in my situation) because the kernel is unable to mount root, and this is caused by it being unable to access the SD interface, as it can't get tim

This isn't a kernel crash, it's just a warning (which I think is safely ignorable). The problem is that QEMU doesn't implement the 'cprman' clock control hardware, which means Linux thinks the UART is running at a zero baud rate. Unfortunately the cprman hardware is as far as I can determine undocu
