+= Getting the entire kernel log on restore media =
+
+The kernel ring buffer that '''dmesg''' reads defaults to 32k on recent kernels. This is not enough to capture the entire sequence of kernel message when Mondo Rescue boots off a restore media.
+
+To increase the kernel ring buffer to 128k at boot time (and without recompilation) add the following kernel boot parameter:
+{{{
+log_buf_len=128k
+}}}
+e.g.
+{{{
+expert log_buf_len=128k
+}}}
+'''dmesg''' needs to be told what buffer size to use to ensure that everything is displayed from the start. The '''-s''' parameter can be used for this like this:
+{{{
+dmesg -s 131072 | less
+}}}
