Thanks for your attention!
The timeout occurs after the first 'shutdown -r' while device probing during second boot process.
Perhaps this is amd64 specific. Today I had a new i386 setup which doesn't exhibit this timeout. But it's on different hardware and hv-host was 5.0 inestead 5.1. So not really representative...

The controller is 'virtual' SAS. But thers's been reports that also on real HW (sasuc8i) the same problem occurs.

I'll try your patch tomorrow morning; timezon shift...
