Description

This is a new Open Indiana installation on a new computer with Intel Corei5 processor

After rebooting, 3 cores on a 4-core system are in a faulted state:

sudo psrinfo
0       faulted   since 04/26/2015 14:21:59
1       faulted   since 04/26/2015 14:21:59
2       faulted   since 04/26/2015 14:21:59
3       on-line   since 04/26/2015 14:21:55

The cores can be brought online with

psradm -n -F 0 1 2

Result:

sudo psrinfo
0       on-line   since 04/26/2015 14:28:32
1       on-line   since 04/26/2015 14:28:32
2       on-line   since 04/26/2015 14:28:32
3       on-line   since 04/26/2015 14:21:55

This is a serious bug. The system has been tested with various tools to make sure there are no hardware problems.
I also tried two different Linux live CDs and both work and enable all 4 cores without issues.

This needs an immediate workaround as it is not feasible to use parsed every type the system reboots and obviously a permanent fix soon.

For completenes - here is cpu_info after the cores have been enabled
