After adding pinctrl_amd module to my initr= amfs I haven't been able to reproduce the problem so far. That may not be indica= tive of anything because the problem does not appear every time. A bit more interesting is my current output of /proc/interrupts. For IRQ9 it currently shows 9: 0 11461 0 0 0 0=20=20= =20=20=20=20=20=20=20 0 0 0 0 0 0 0 = 0=20 0 0 IR-IO-APIC 9-fasteoi acpi, pinctrl_amd Notice that the number of recorded interrupts is around 11000. Before I add= ed pinctrl_amd to initramfs, there were two distinct cases. Either over 100000 interrupts with the kernel complaining about IRQ9 not being serviced or abo= ut 90 interrupts and no apparent issues. All of these numbers are from /proc/interrupts dump done right after logging into DE after a reboot. I was able to reproduce these figures multiple times. This suggests that so= me HW starts to blast IRQs and doesn't stop until it gets serviced. Knowing th= is, is there anything else you'd like me to try besides your suggestions above? My CONFIG_PINCTRL_AMD is set to CONFIG_PINCTRL_AMD=3Dm in my kernel config = and the respective module is loaded. --=20 You may reply to this email to add a comment.
