Your kernel message buffer is too small to store the entire verbose boot
sequence in memory before syslog can extract it. It's a circular buffer, so
new entries overwrite the oldest ones. The line just before the "ACPI:
MCFG" line was probably another ACPI line that happened to end in 8 and a
close-paren. Adding this to your kernel and rebuilding should let you see
the entire boot output. If something's still truncated, double it and try
again.
