Kernel gurus,

Since the boot process on some SMP machines can be rather verbose, it seems
that the ring buffer for printk()s wraps before it can be snarfed by
klogd/syslogd after boot.
This makes it difficult to troubleshoot messages printed early in the boot
process (like BIOS RAM maps).

The default buffer size is 16k. (kernel/printk.c, line 26)
Would it be reasonable to increase this to 32k (or more) on most machines?

The buffer size is set at compile-time, and may present a problem in
limited-memory (embedded?) systems if grown too large.

Comments are most welcome.

Tim
