After an install of Winston Beta-3 on an Ultra5 (128MB, 8GB IDE), the boot process stalls at: Starting NFS lockd: The usual STOP+A (L1+A) doesn't appear to drop me back to OpenBOOT, so I have no idea how to proceed, other than power-cycling the machine. I'm leaving it overnight to see if it ever recovers. The only relevant details I can think of: this was a custom graphical installation, and "NFS server" was NOT selected. I configured this machine during the install to use DHCP... it is past the eth0 initialization so I don't know if that's the problem or not. More details cheerfully provided on request, but this pretty much makes Beta-3 unusable on my Sun Ultra. The little yellow sun on Tux's belly is cute, though.
Didn't recover overnight, so I'm assuming it's well and truly hung.
Brock Organ confirmed on testers-list that this is a known SPARC problem. Sun themselves reported seeing it after their testing. Without a fix for this, Winston SPARC can't really be tested at all.
This was actually glibc and kernel issue.
