This happens on every other boot for me. When it happens it always happens when loading nvidia driver. <118>Mounting local filesystems:. <118>Mounting ZFS filesystems: (354/354) <118>Loading kernel modules: nvidia0: <NVIDIA GeForce GTX 1660> on vgapci0 vgapci0: child nvidia0 requested pci_enable_io vgapci0: child nvidia0 requested pci_enable_io <6>nvidia-modeset: Loading NVIDIA Kernel Mode Setting Driver for UNIX platforms 550.54.14 Thu Feb 22 01:05:40 UTC 2024 sysctl_warn_reuse: can't re-use a leaf (hw.dri.debug)! <6>[drm] [nvidia-drm] [GPU ID 0x00000100] Loading driver Memory modified after free 0xfffff800207cf900(376) val=1010000 @ 0xfffff800207cf900 panic: Most recently used by solaris cpuid = 2 time = 1716443221 KDB: stack backtrace: db_trace_self_wrapper() at 0xffffffff80614c2b = db_trace_self_wrapper+0x2b/frame 0xfffffe01985cc060 kdb_backtrace() at 0xffffffff8094a037 = kdb_backtrace+0x37/frame 0xfffffe01985cc110 vpanic() at 0xffffffff808fba29 = vpanic+0x169/frame 0xfffffe01985cc250 panic() at 0xffffffff808fb803 = panic+0x43/frame 0xfffffe01985cc2b0 mtrash_ctor() at 0xffffffff80bb25ee = mtrash_ctor+0x7e/frame 0xfffffe01985cc2d0 item_ctor() at 0xffffffff80bb1818 = item_ctor+0x108/frame 0xfffffe01985cc320 uma_zalloc_arg() at 0xffffffff80baac3b = uma_zalloc_arg+0x10b/frame 0xfffffe01985cc360 malloc() at 0xffffffff808d4f60 = malloc+0x70/frame 0xfffffe01985cc3a0 os_alloc_mem() at 0xffffffff857de5f7 = os_alloc_mem+0x37/frame 0xfffffe01985cc3c0 _nv013606rm() at 0xffffffff854fc874 = _nv013606rm+0x34/frame 0xfffffe01a322fc00 Uptime: 42s "Most recently used by solaris" makes me think that the problem is in ZFS.

Did you install the nvidia driver from ports or from packages? How do you load it? Have you tried another load options? Have you tried other driver versions?
(In reply to Vladimir Druzenko from comment #1) nvidia driver is only a victim here, it simply allocates memory and the allocator sees that the memory has been tampered with.
