Hi folks -- I hope someone has experience with this; I'm at the end of
my rope!
Briefly, one our 3B2/310's crashed this summer, and I finished reloading the
system (UNIX Sys V Rel 3.0) and user files. Everything works fine, EXCEPT those
programs I compiled using the C-FP+ Compilation System ('fpcc') which
compiles code for the 32100 with the 32106 math accelerator unit (MAU).
Whenver I try to run an executable created by fpcc (include exact copies
of those created before the crash) I get:
rn: cannot execute
It turns out the exec(2) call is failing with EFAULT, meaning "required
hardware not present". To date, I have:
+ Run diagnostics on the MAU -- it checks out fine,
+ Made sure the MAU driver is contained in the kernel,
+ Run "crash" and examined the kernel variable "mau_present" --
it's value is "1", the same as our other 3B2's with the MAU, and
+ Tried nasty tricks like removing the MAU and 32100 flag bits
in the programs' 'filehdr' -- still doesn't work!
Has anyone ever had an experience like this? Any ideas? My *last* resort
is AT&T tech support...I can't even imagine working through the proper
channels with such a bizarre problem...
Thanks in advance, Don

Since I have made similar statements concerning AT&T's tech support, I sort of feel I must defend them here. If you can get them to have a tech from Lisle (Illinois) contact you, they are VERY good at tracking down the bizarre, and handle it very enthusiastically compared with the call- takers who just expect to send someone out to swap boards.
