Booting 1.8 REL on a Thinkpad 600E gives an endless loop of ACPI errors:
(by hand)

ACPI Exception (evregion-0529): AE_TIME, Returned by Handler for
[EmbeddedControl] [20061109]
ACPI Error (psparse-0638): Method parse/execution failed
[\_SB_.PCI0.ISA0.EC0_.I2RB] (Node 0xc1084e78), AE_TIME
ACPI Error (psparse-0638): Method parse/execution failed
[\_SB_.PCI0.ISA0.EC0_.UPDT] (Node 0xc1084dd0), AE_TIME
ACPI Error (psparse-0638): Method parse/execution failed [\_TZ_.THM0._TMP]
(Node 0xc1084a10), AE_TIME

These may be out of order, since it's looping on these messages and I
can't tell where one starts and the other stops.  Hitting ctrl-alt-del
started the normal shutdown process, which makes me think it was the
console getting spammed with messages.

Booting with ACPI off removes the messages, not surprisingly.  This laptop
booted 1.4, I think it was, with ACPI on.

Booting 1.8 using VMWare Fusion on OS X works fine.

Both systems showed messages like this at shutdown of the LiveCD:
(this one's from the VMWare environment)
unmount(/dev): Cannot unmount: 0 namecache references still present
unmount(/dev): Cannot unmount: 5 process references still present
unmount(/var): Cannot unmount: 0 namecache references still present
unmount(/var): Cannot unmount: 5 process references still present

and after the disk sync:
unmount(0xc12d57c0): Forced unmount: 2 namecache references still present
unmount(0xc12d57c0): Forced unmount: 4 process references still present
EXDEV case 1 0xc10c4238
