The bug resurfaced between qemu-7.1.0 and qemu-7.2.0 after commit f3639a64f602 ("target/arm: Use softmmu tlbs for page table walking"), but may be caused by the preceding 4a35855682ce ("target/arm: Plumb debug into S1Translate") which fails to boot for an unrelated reason. + +I reproduced this on qemu-7.2 as shipped by Debian as well as on qemu-9.1 (built locally). + +Part of this problem appeared to be hidden by the 'highmem=on' argument not having the intended effect during parts of the bisection, which I worked around by overriding the 'pa_bits' variable in machvirt_init(). |
