The guest performs fine before the reboot. + +Closer examination reveals that no hardware interrupts are delivered to the guest. BIOS Data Area variables like the keyboard buffer and the system clock are not updated. Even non-maskable interrupts fail to be delivered, as witnessed by installing an option ROM that hooks interrupt vector 2 and issuing the `nmi` command in the monitor. + +The only remedy seems to be to exit the QEMU process entirely and launch it again. +Steps to reproduce: +0. Install Windows 98 into the guest. (Since the normal installation process already involves a couple of reboots, it is possible to hit the issue already at step zero.) +1. Boot it; it may be into Safe Mode, but the protected-mode graphical environment must at least attempt to load. (I managed sometimes to reproduce the bug without the system having loaded fully.) +2. Reboot. This may be a clean reboot, or it may be a hard reboot (`system_reset` or equivalent) +3. Observe the system freeze. +Additional information: +None |
