>Release: FreeBSD 2.2.5-RELEASE i386
>Environment:
Custum kernel (same configuration on 2.2.2-R and 2.2.5-R),
ibcs2 emulation loaded as a lkm.
Upgrade to 2.2.5-R was done by removing /usr/src, copying the
new sources and executing "make world".
>Description:
The C-compiler from SCO-Openserver 5.0.2 works under
FreeBSD 2.2.2-R but fails after upgrading to 2.2.5-R with
the following error message:
libsocket: socket: /dev/socksys: No such file or directory
/compat/ibcs2/usr/ccs/lib/acomp: ERROR- Failed to initialize
policy manager.(IFOR_PM_FATAL)
Booting the 2.2.5-R system with an old 2.2.2-R kernel solves the
problem.
The following output from ktrace/kdump shows the differences
between 2.2.2-R and 2.2.5-R:
FreeBSD 2.2.2-RELEASE:

acomp CALL write(0x2,0xefbfd9e8,0x13)
acomp GIO fd 2 wrote 19 bytes

acomp RET write 19/0x13
...
>How-To-Repeat:
If you have access to SCO's C-compiler try:
/compat/ibcs2/usr/ccs/lib/acomp -i xx.c -o xx.s -f xx.c -E
-y0/usr/include -Qy -Xa
>Fix:
No idea. The files in /sys/i386/ibcs2 did not change between
2.2.2-RELEASE and 2.2.5-RELEASE so the problem must be somewhere
else in the kernel sources.
