Cross-posted to ZFS-Discuss per Vikram's suggestion.
Summary: I upgraded to snv_123 and the system hangs on boot. snv_121, and
earlier are working fine.
Booting with -kv, the system still hung, but after a few minutes, the system
continued, spit out more text (referring to disks, but I could not capture the
text). Here is what was left on the screen once the debugger kicked in:
PCI Express-device: i...@0, ata0
ata0 is /p...@0,0/pci-...@14,1/i...@0

operating system: 5.11 snv_123 (i86pc)

DTrace state: inactive

To clarify, when build 122 was announced, I tried upgrading. The new BE would
not boot, hanging in the same way that snv_123 does. I later deleted the
snv_122 BE.
Also, I checked my grub config, and nothing seems out of line there (though I
have edited the boot entries to remove the splashimage, foreground, background,
and console=graphics).
Thanks,
