#7478: [USB] Haiku does not boot on Gigabyte MA78LM-S2 ---------------------------+------------------------------- Reporter: silentjohn | Owner: mmlr Type: bug | Status: new Priority: normal | Milestone: R1 Component: Drivers/USB | Version: R1/Development Resolution: | Keywords: usb, sb700, sbx00 Blocked By: | Blocking: Has a Patch: 0 | Platform: x86 ---------------------------+------------------------------- Comment (by silentjohn): Replying to [comment:2 mmlr]: > What exactly happens there? Does it stop there or does it continue very slowly? If it continues extremely slowly then it's either an OS interrupt storm or an SMI storm hanging or almost hanging the system due to it looping through the interrupt handlers continuously. Possibly disabling interrupts completely using the disable-interrupts register as well as acknowledging any possibly pending interrupt before writing the ownership change request could avoid that. It is also possible that the ownership change itself works, but the reset triggers the interrupt storm (would be pretty wired to implement it that way though). It seems to me that boot halts completely. I can't confirm the extremely slow boot because I left it only for 1-2 minutes in this state. I can restart the machine only with pushing the reset button. -- Ticket URL: <http://dev.haiku-os.org/ticket/7478#comment:3> Haiku <http://dev.haiku-os.org> Haiku - the operating system.
