I have a sunblade1500 with OBP version 4.16.4 that I'm trying to install gentoo on. I started off with OBP version 4.9.5 and the cd booted fine. I got the install to complete successfully, but could not get silo to boot. I scoured the net and tried all (valid) suggestions with no success. The final suggestion I tried was updating OBP. I upgraded to the version above and now the sparc64-universal-2004.3 cd fails with "clock_probe: Could not find timer chip". When we put the hdd with solaris on it, it boots fine. Here is a link http://forums.gentoo.org/viewtopic.php?t=282777&highlight=silo to my posting on the gentoo forum. It has a more detailed explanation of the whole issue. Reproducible: Always Steps to Reproduce: 1.ok boot cdrom 2. 3. Actual Results: clock_probe: Could not find timer chip Expected Results: Live cd should have loaded so I could chroot into my gentoo env and try to fix silo. http://forums.gentoo.org/viewtopic.php?t=282777&highlight=silo
