Little bit of a follow up.

Summary of my previous notes

I installed 5.2ML4 on a 7043-260 and the system failed to boot. It
hangs with the message "AIX is starting" in the operator display window

Current status:

I can boot a installation CD but when I enter maintenance mode and mount
/usr, the system starts giving messages like shown below. All commands
fail with the same messages.

Two different install CDs fail with the same messages. fsck on /usr
(and the other filesystems) runs clean.

Could not load program sh:
Symbol resolution failed for /usr/lib/libc.a(shr.o) because:
Symbol projctl (number 143) is not exported from dependent
module /unix.
Symbol getpeereid (number 239) is not exported from dependent
module /unix.
Symbol shm_open (number 305) is not exported from dependent
module /unix.
Symbol shm_unlink (number 306) is not exported from dependent
module /unix.
Symbol mq_close (number 307) is not exported from dependent
module /unix.
Symbol mq_unlink (number 308) is not exported from dependent
module /unix.
Symbol mq_getattr (number 309) is not exported from dependent
module /unix.
Symbol mq_setattr (number 310) is not exported from dependent
module /unix.
Symbol mq_send (number 311) is not exported from dependent
module /unix.

Before I give up and reinstall, does anyone have any ideas on how to
avoid the reinstall process?

Has anyone successfully installed 5.2ML4 or has IBM screwed the pooch on
this?
