I am testing Fedora rawhide in a xen pv guest and I get the error
[ 9.809550] genirq: Flags mismatch irq 8. 00000000 (hvc_console) vs.
00000000 (rtc0)
[ 9.809714] hvc_open: request_irq failed with rc -16.
during the boot and the hvc console doesn't respond when the boot
finishes. I have noticed this I think since the update through various
linux 4.4.0 kernels up to the current 4.4.0-0.rc5.git3.1.fc24.x86_64 one.
I do get an hvc console if I use the Fedora 23 kernel 4.2.6-300.fc23.x86_64
from before the update.
Is this a known problem? I have attached the boot log up to the above
error.
