Hanging on bootup with IGM T43. Gets to
Loading /boot/initrd.gz..............

when booting from a USB flash drive, then stops. I have used the same flash drive to boot the T60, a few T42s and some no-name chassis and IBM servers without issue.

After a bit of searching, came across multiple references to acpi=off in the boot line--didn't fix the boot hang. Any help would be appreciated.
