Description Tom Zanussi 2010-10-14 09:37:47 UTC 
The current kernel log buffer (dmesg) size is only 16k (LOG_BUF_SHIFT=14), which seems too small for the Atom-based BSPs - a few verbose errors on bootup can easily cause the most interesting debug messages to be lost.

A larger value would be better (LOG_BUF_SHIFT=17 (132k) would be good, or 16 (64k) at minimum).
Comment 1 Tom Zanussi 2011-01-18 07:40:03 UTC 
Added logbuf feature to kernel, see kernel commit 5adcf6fbcd7491d8d3e1805929f575041d439235.
