Three V10-r4 crash reports on their way

[tallbs]

Decided to try V10-r4 after problems with fib lines disappearing in earlier v10 release.

Ran install from download file - no error msgs.
Normal Reboot - try esignal - crash one.
Reboot - try esignal - crash two.
Try repair - it ran for 3-4 mins - reboot - try esignal - crash three.

Back to V8 again.....three crash reports sent.
