Description Martin Mokrejš 2012-01-25 10:54:54 UTC

The output of "dmesg" command is sometimes not complete (the very beginning is missing) when size of the buffer is overflowed. Comparing the /proc/config.gz with my own .config suggests you should change the following variable:

-CONFIG_LOG_BUF_SHIFT=15
+CONFIG_LOG_BUF_SHIFT=17


I am talking about the "x86" kernel at least.
