NetBSD 5.0_BETA (INSTALL) #0: Sat Jan 24 19:33:06 CET 2009

>Description:
I get a panic in ffs_itimes when installing 5.0_BETA on amd64, iff I use mount 
options "log" for the filesystems. The panic occurs when choosing where to get 
the installations sets from, or later in the installation.

Once installed (without logging), the system seems to work even with logging 
enabled. I have not seen this problem when installing with an i386 install 
kernel (on the same hardware).

The panic occurs in line 748 of sys/ufs/ffs/ffs_inode.c when trying to access 
ip->i_ump->um_fstype in the first DIP_ASSIGN() of this block:

        if (ip->i_flag & (IN_CHANGE | IN_MODIFY)) {
                if (cre == NULL)
                        cre = &now;
                DIP_ASSIGN(ip, ctime, cre->tv_sec);
                DIP_ASSIGN(ip, ctimensec, cre->tv_nsec);
        }


ddb output:
