I just updated our 350 to UP-UX 6.01 and found what appears to be a
bug in the DIL library call "io_burst". When both a raw buss and addressed
device file are opened on the same interface the interface is locked until
the system is rebooted. After the system locks up an interface the system
crashes if io_burst is turned on again. Example:
main()
{
int eid; /* I took out all the error checking for simplicity */
int reid;
reid=open("/dev/hpib7",2);
eid=open("/dev/hpib711",2);
io_burst(reid,1);
io_burst(eid,1);
}
Try running the little program twice- you won't like it the second time!
Does anyone know of a fix for this mess? Is there an address for Bill or
Dave? Better yet, Does anyone have John Young's address? I'd like to write
a "Dear John" letter! I've delt with io_burst problems with 5.1, 5.2, 5.3,
5.5 and 6.0. My personal income is at stake!! The above example is only
one that will crash the system, io_burst is sick.
I think HP should fix DIL or stop selling it...

I am submitting 4 bug reports related to I/O and would like
to know if HP is interested in fixing DIL in HP-UX on the s300.
Two of the bugs have been passed on- the remaining two are on
their way.
Does anyone here me! Or is realtime UP-UX just lip service...

Sorry if I sounded a bit grumpy. But, after all, its been almost a year and about 4 revisions of hp-ux with a crippled io_burst. Something tells me that DIL will be as sound as the rest of the system in rev. 6.2 ! Jeff () Harrell hpubvwa!weycord!jeffh
