It looks like clog is failing to recognize its own file header somehow.

: clog system.log
CLOGI���Oct  9 12:36:13 pfSense syslogd: kernel boot file is /boot/kernel/kernel
clog: ERROR: could not write output (Bad address)
: cat system.log
CLOGI���Oct  9 12:36:13 pfSense syslogd: kernel boot file is /boot/kernel/kernel

Upgraded installs seem to be OK, only new installs from around Friday or later are affected.

It's also possible syslogd is writing bad data to the file which breaks the clog format, so maybe the syslogd clog patch didn't make it to the 11.1 tree. If that were the case I'd expect upgrades to be broken as well, however.

Luiz pushed some fixes to clog to correct this, next new snapshot we're testing internally is good.

#define ENODEV 19 /* Operation not supported by device */

if (memcmp(&(f->f_un.f_ring.f_footer->cf_magic),MAGIC_CONST,4)!=0) {
(void)munmap(f->f_un.f_ring.f_footer,sizeof(struct clog_footer));
(void)close(f->f_file);
f->f_type = F_UNUSED;
errno = ENODEV;
logerror(p+1);
break;
}

So if the CLOG magic is missing CLOG will return ENODEV and spit the error message. The original issue that Luiz fixes was that syslog (clog) was writing after the end of buffer and the 'magic was overwritten.
