It shows what the kernel is currently is doing and where it's spending the
time.
First, your kernel buffer log buffer seems a little small, so not
everything is captured. Could you increase the number in the "Kernel log
buffer size" option (it's in the "Kernel debugging" part of the "Kernel
hacking" menu).
Second, could you press ALT+PrintScreen+P a few more times (maybe around
10 at least) while the kernel hangs? This would should where the cpu is
spending its time and whether it's at a single place or at different
places.
Thanks.
bye, Roman
