Hello,
While upgrading from source my 13-CURRENT box from ALPHA1 to BETA1, I
got the following crash on make installworld.
Fatal trap 12: page fault while in kernel mode

127 if ((pp->acw + dw) > 0 && pp2->ace > 0)
(kgdb) p pp2
$2 = (struct g_provider *) 0x0
pp2 is null, and pp2->ace crashes the system.
Does the above crash pattern rings any bell? My system uses UFS SU+trim on GELI.
On reboot, I had to manually run fsck. At the end I did reinstall
successfully world from my poudriere server through NFS, since I wasn't
sure about the state of the files in /usr/obj...

Ali
