https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=271826 --- Comment #20 from Justin Hibbits <jhibbits@FreeBSD.org> --- (In reply to Sergey Fedorov from comment #15) Unfortunately I think the number of committers with PowerMac G5 hardware supporting FreeBSD is dwindling as the machines age. My only G5 that ran FreeBSD died back in 2018, so I'm unable to do anything significant for it. That said, I'll support as best as I can. Regarding the "USB error upon intro screen load" that's often solved by unplugging/plugging the device (happens all the time with one of my FTDI debuggers), not a problem with FreeBSD itself. The "Root mount waiting for usbus2", unless you have root on USB you can try setting the hw.usb.no_boot_wait tunable; it looks like usbus2 is having enumeration problems (just a guess). For 13.x performance, you can try testing a commit before, and after, c583b02587 (PowerMac timebase sync for G4), which should be a nop for G5, but might not be. Other possibilities are pmap related (superpage support was added in the 13 timeframe, I believe). -- You are receiving this mail because: You are the assignee for the bug.home | help
