Yes, for me on my 2-socket G4, it gets as far as mounting the root filesystem and starting filesystem checks before it hangs. I still need to set up dcons there and poke around a bit. > > Before, 2-socket died much earlier.

I do know there is a bug somewhere in bridge mode that corrupts things when running 32 bit on a G5 processor, but G3 and G4 should still be working fine... Is this with an up-to-date userland? I do know there were some atomic issues in userland at one point, but they should all be sorted out now. > > Anyway, I've a bunch of SSDs to update so the basic > problem does not reappear if I grab another one. > > === > Mark Millard > marklmi at yahoo.com > ( dsl-only.net went > away in early 2018-Mar) > > -- Brandon Bergren [email protected] _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-ppc To unsubscribe, send any mail to "[email protected]"
