I have had one crash, but I am not at all sure that it had
anything to do with the frontend crashing as it seems to
be an arm crash discovered in StopHWFilter. I haven't
investigated this further, maybe someone else can tell more.
I'll attach the log below.

Here goes:
channel switchings: 460
lock ups: 28
recovered: 23
crashes: 0

Delays (usec: count):
0: 5
20: 67
30: 80
40: 122
50: 129
60: 48
370: 1
400: 1
410: 3
420: 1
430: 1
440: 1

I made the statistics with:
% grep 8870 /var/log/messages | grep lockup\! | wc
% grep 8870 /var/log/messages | grep lockup\ recov | wc
% grep 8870 /var/log/messages | grep Delay | awk '{print $8}' |
sed 's/(//' | sort -n | nawk 'BEGIN {x = -1} {if ($1 == x)
{ n = n + 1; } else { if ( n > 0 )
 { print x ": " n } x = $1; n = 1;} }'
