Description
|
Booting off DVD (S10_U1 Build 17) on certain X86 machines causes a hang during Configuring Devices ~80% of the time.
Seen on:
line2-w1100z linei-w1100z (metropolis)
and wbox
To reproduce:
Try boot off "Solaris 10 10/05 DVD" Build Beta3 X86 on any of machines above.

Work Around
|
boot -dk and set mtc_off to 1. Apply same in etc/system on installed
system. While tempting this workaround can not be incorporated into
the shipping bits as it would severely regress large system boot-time.
Another potential workaround (though it castrates the system) is to set use_mp=0 in /etc/system. Another alternative that may work (and has worked, at least on the metropolis) is to prevent the apic_redistribute_intr cyclic from being added by disabling oneshot timing in pcplusmp (set pcplusmp:apic_oneshot_enable=0), but this, too, has bad side effects for running systems (high-resolution timing for things like dtrace won't work).
