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... > Extra printfs affect the timing most likely. > > Are you using any RAID volumes? The only shutdown handler in mpt that = looks 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... Thanks, -Harry=
