Typo in a kprintf? ;)

Are you perchance on an SMP system (which includes a 1-CPU HT)?  There's a few
race conditions when processes on both/multiple processors printk() at the same
time.  Other possibility is a burst of traffic wrapped the kernel syslog buffer
before klogd read it.  On recent kernels, you can tune how big the buffer is at
kernel build time with CONFIG_LOG_BUF_SHIFT (16 for a 64K buffer, 17 for 128K,
etc).
