There were no i386 specific commits in this time frame, especially no Meltdown fixes. There was an "update ttm and radeondrm(4) to Linux 4.4.129" commit and I know that it was tested before in snapshots. So it might be related to that. I see these lines in your dmesg: radeondrm0 at pci1 dev 0 function 0 "ATI Radeon Mobility M7" rev 0x00 drm0 at radeondrm0 radeondrm0: irq 11 Are you using X11 on this machine? I think it is worth trying wiithout drm. Disable it in UKC. At the boot prompt boot enter -c: boot> boot -c booting hd0a:/bsd: 9157387+2208772+192532+0+1101824 [708103+98+518752+539082]=0xdc44ac With a kernel that shows the problem, disable drm at the UKC prompt: avail mem = 2091601920 (1994MB) User Kernel Config UKC> disable radeondrm 252 radeondrm* disabled UKC> quit Continuing... mpath0 at root After that ATI should attach to vga. Please send the complete dmesg when booting with this tweak, so we can see that disabling drm worked. Does it affect whether the crash happens? bluhm
