#8085: SMI storm on USB handover on AMD 970/SB950 AMD AM3+ UEFI motherboard -----------------------------+----------------------------------------- Reporter: kallisti5 | Owner: mmlr Type: bug | Status: in-progress Priority: normal | Milestone: R1 Component: System/Kernel | Version: R1/Development Resolution: | Keywords: SB950,UEFI, AHCI, APIC, IRQ Blocked By: | Blocking: Has a Patch: 1 | Platform: All -----------------------------+----------------------------------------- Comment (by kallisti5): Replying to [comment:15 mmlr]: > While I agree that disabling all interrupts may very well be a problem, not disabling them at all is not an option. The reason why they are disabled is that we don't want to get interrupts while we haven't set up an interrupt handler yet and therefore would cause an interrupt storm on our end when the handover happens and doesn't clear the interrupts. Hence disabling everything besides the ownership change would possibly work. Yup.. Attaching the current patch I'm playing with. Don't worry, I wouldn't commit anything like this until extensive testing and review :) -- Ticket URL: <http://dev.haiku-os.org/ticket/8085#comment:16> Haiku <http://dev.haiku-os.org> Haiku - the operating system.
