On Sun's Cobalt LX50 the 1.4_rc2 livecd hangs indefinetely (more than 30 minutes) after printing "Using module cloop.o". The CDROM drive seems to seek, but the system is inresponsive.
have you tried acpi=off and noapic on this box?
Yes. All the advertized no- flags (net,apic,acpi).
Have/Can you try one of the latest experimental livecds?
