I built a powerpc (non-64) 11.0-CURRENT -r280598 SSD (via gcc 4.2.1, not = 4.9.1) and it has worked okay in G4 PowerMac's that I've tried. (I have = no prior 11.0-CURRENT non-64 powerpc G4/G3 history, but do have a little = for for the G5's.) I'm counting here PowerMac's that 10.1-STABLE works = fine for, as did older builds going back to 10.0-STABLE. But the SSD does not boot in the iMac G3 that I tried. Nor in the = PowerMac G5's. Likely different reasons, even based on the little = information that I have so far. It may be some time before I get to having much information but what I = have now is: The below are all for the same SSD plugged in different = PowerMac's/iMac's and then used to boot, not changing the software = between times. PowerMac G4's: No problems so far. (Note: I've access to one PowerMac G4 that I'm ignoring here. While Mac = OS X and Lubuntu have never had troubles with it, every FreeBSD build = that I've tried from back in 10.0-STABLE times when I started to now = hangs during the boot sequence, fairly early.) iMac G3 (I've access to only one example G3): After > Time counters tick every 1.000 msec it gets: > [Thread pid 0 tid 100037] > Stopped at pmap_activate+0x7c lwz r11,r1,0x0 which may be reporting the instruction after a indirect subroutine jump. PowerMac G5's: Unlike the past where things worked overall the build now gets to the = point of just mostly reporting timeouts, retries, and such for ada0 = (where the SSD is plugged in). This is fairly early in the boot = sequence. Notably some ata support has been removed from 11.0-CURRENT according to = the UPDATING notes, supposedly replaced with better support. But many = FreeBSD statements implicitly mean "tier 1" as the implicit context and = have other implications elsewhere. I've no clue in this case yet. So far powerpc64 11.0-CURRENT -r280598 has not had such problems when = used with the same PowerMac G5's. =3D=3D=3D Mark Millard markmi at dsl-only.net
