[Emc-developers] Weirdest lcnc problem yet

[Gene Heskett]

Greetings all;

My GO704 box has decided it cannot find the RTLIB modules.

I have tried to export the path in both my own .basrc, and in 
/etc/profile, but the only way to make it show up in an "env" 
output is to export it from the command line of every terminal, 
AND terminal window tab that I open.  And even that does not help.

It simply cannot find hm2_pci.ko according to the messages it emits as 
its cleaning up.  It leaves this in the window that tries to run it:
=

I've looked at /usr/bin/linuxcnc and that path is correctly specified 
in that startup script.  The module in question is there at that location, 
along with about 100+ other.ko's.  First encountered after I had added
a "loadrt estop_latch count=1", which did not error until it hit the 
addf estop_latch.0 servo-thread
statement.  Both are currently # commented out of the .hal file now. 

I had this same problem 5 or 9 times on the older crashomatic box, just 
one of the reasons I set it out the back door for disposal, after I 
collect the good stuffs in it,but this is a Dell 745, with 4Gb of DDR-2 
ram that passed 9 cycles of memtest86+ in an overnight run just 2 days ago.

With the old box, a full power down reboot would fix it, for several hours.
But that doesn't seem to fix this Dell.  Its had 2 30 second plus 
powerdowns since it first started doing it

I just took both lines out of the $CONFIG/$CONFIG.hal file, made zero
difference.

The old man is about beat.  What do I look at next? 

Its a 6 months old 2 terrabyte Seacrate drive, with about 60 hours on it 
now, and very fast.

Humm, uname -a looks confused:

gene@GO704:~/linuxcnc/configs/GO704fast$ uname -a
Linux GO704 3.4-9-rtai-686-pae #1 SMP PREEMPT Debian 3.4.55-4linuxcnc i686 
GNU/Linux

WTF?

FWIW, sudo dmesg|less is also confused, lines 3 nd 4 look interesting:
[ 0.00] Linux version 3.4-9-rtai-686-pae (Debian 3.4.55-4linuxcnc) () (gcc 
version 4.6.3 (Debian 4.6.3-14) ) #1 SMP PREEMPT Debian 3.4.55-4linuxcnc
[ 0.00] Disabled fast string operations

I have an enigma wrapped in a puzzle sort of a headache.

Ideas?  Fixes?  Geneaology references?

Thanks guys.

Cheers, Gene Heskett

It was Peter, the cards P.O.S. retainer had flipped open and it was out 
of the socket.

It was missing when I thought to do that after posting.

You might want to whistle in the S & R dogs and drink that barrel of 
whiskey yourselves, I think I have found it.

The whole back panel that carries the card holddown brackets is A, 
somewhat of a sloppy fit as the whole thing is a slide-out panel.  B, It 
contains a plastic cam latch that supposedly locks the card brackets 
screw slot onto a tit sticking up at the same location one normally 
expects to see a holddown screw.  My wrestling with a recalcitrant tight 
fitting DB-25, combined with a few bumps against the wall behind it as I 
was restoring its position on the shelf, had both flipped the plastic 
cam loose, and jacked the cards rear end up out of the mainboard socket 
so it wasn't being recognized by an lspci.

So I need to figure a way to nail it down solid enough it can't be pried 
out of the socket while wiggling that connector on & off.

My apologies & thanks guys.

That normally means it cannot find the FPGA card
most often this is a PCI contact issue

Check with lspci -vn | grep 5125

( should print something with 2718:5125 )

occasionally its because of a marginal 3.3V ATX PS
( symptoms of this are the red lights on 5I25 staying on or blinking any time 
other than power up)
