Sorry to be rather late to the party; the Internet connection I'm using
at the moment is a bit flaky. (I'm out of town.)
I managed to get head/i386 @r254135 built and booting ... by removing
the "options DEBUG_MEMGUARD" from my kernel.
However, that merely prevented a (very!) early panic, and got me to the
point where trying to start xdm with the x11/nvidia-driver as the
display driver causes an immediate reboot (no crash dump, despite
'dumpdev="AUTO"' in /etc/rc.conf). No drop to debugger, either.
Booting & starting xdm with the nv driver works -- that's my present
environment as I am typing this.
However, the panic with DEBUG_MEMGUARD may offer a clue. Unfortunately,
it's early enough that screen lock/scrolling doesn't work, and I only
had the patience to write down partof the panic information. (This is
on my laptop; no serial console, AFAICT -- and no device to capture the
output if I did, since I'm not at home.)
The top line of the screen (at the panic) reads:
s/kern/subr_vmem.c:1050
The backtrace has the expected stuff near the top (about kbd, panic, and
memguard stuff); just below that is:
vmem_alloc(c1226100,6681000,2,c1820cc0,3b5,...) at
0xc0ac5673=vmem_alloc+0x53/frame 0xc1820ca0
Caveat: that was hand-transcribed from the screen to papaer, then
hand-transcribed from paper to this email message. And my highest grade
in "Penmanship" was a D+.
Be that as it may, here's the relevant section of subr_vmem.c with line
numbers (cut/pasted, so tabs get munged):
1039 /*
1040 * vmem_alloc: allocate resource from the arena.
1041 */
1042 int
1043 vmem_alloc(vmem_t *vm, vmem_size_t size, int flags, vmem_addr_t *addrp)
1044 {
1045 const int strat __unused = flags & VMEM_FITMASK;
1046 qcache_t *qc;
1047
1048 flags &= VMEM_FLAGS;
1049 MPASS(size > 0);
1050 MPASS(strat == M_BESTFIT || strat == M_FIRSTFIT);
1051 if ((flags & M_NOWAIT) == 0)
1052 WITNESS_WARN(WARN_GIANTOK | WARN_SLEEPOK, NULL,
"vmem_alloc");
1053
1054 if (size <= vm->vm_qcache_max) {
1055 qc = &vm->vm_qcache[(size - 1) >> vm->vm_quantum_shift];
1056 *addrp = (vmem_addr_t)uma_zalloc(qc->qc_cache, flags);
1057 if (*addrp == 0)
1058 return (ENOMEM);
1059 return (0);
1060 }
1061
1062 return vmem_xalloc(vm, size, 0, 0, 0, VMEM_ADDR_MIN,
VMEM_ADDR_MAX,
1063 flags, addrp);
1064 }
This is at r254025.
Peace,
