|I've been experimenting with the 64bit UL on Sparc, and have hit an issue booting via GRUB.
I've been following the handbook installing the new system, and have installed grub according to the documentation. However, when trying to reboot, it just hangs:
Sun Ultra 60 UPA/PCI (2 X UltraSPARC-II 450MHz), No Keyboard
OpenBoot 3.17, 1024 MB memory installed, Serial #1xxxxxxx.
Ethernet address 8:0:20:x:x:x, Host ID: 80xxxxxx.
Rebooting with command: boot
Boot device: disk File and args:
GRUB Loading kernel..
Sending a break signal does nothing; I have to hard power-cycle to recover. This is a headless system with serial console - maybe grub is trying to show the graphical boot menu? Fortunately I can still boot using silo on the second disk, but that's not a permanent solution. This is the output I get when trying to run grub-install:
|# grub-install --target=sparc64-ieee1275 --recheck --force --skip-fs-probe /dev/sda1
Installing for sparc64-ieee1275 platform.
grub-install: warning: Discarding improperly nested partition (hostdisk//dev/sda,sun1,sun2).
grub-install: warning: Discarding improperly nested partition (hostdisk//dev/sda,sun1,sun4).
grub-install: warning: Discarding improperly nested partition (hostdisk//dev/sda,sun1,sun5).
grub-install: warning: Attempting to install GRUB to a disk with multiple partition labels. This is not supported yet..
grub-install: warning: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and their use is discouraged..
Installation finished. No error reported.
As a secondary issue (when I do get it booted) only one CPU is detected by Linux, but I should probably make a separate thread for that.
