This is one of those problem reports I hate sending and one that I
know everyone hates receiving. I have gone over and over my settings
and I'm certain that I haven't done anything stupid, so please bear
with me.
I recently upgraded a machine from an old 3.0-RELEASE to the 20000209
snapshot. It was previously running a Boca BB2016 multiport serial
card ("box" actually) correctly. Now the master port (16) on the card
works but none of the others seem to generate interrupts. I put a
printf at the beginning of siointr() and when I plug the modem into
the master port and talk to it with cu, it works fine and I get
messages from my printf signifying that siointr() was called with
((struct com_s *)arg)->unit = 17.
When I do the same with the other ports, siointr() is never called. I
get some characters back from the modem, but only when I press a key:
for instance I type "A" get nothing, type "T", get A, type "RET", get
T, type RET again and finally get \nOK\n. If I type ati10\n which
should give back a screenfull of stuff, I get about 16 characters
printed in cu and a silo overflow on the console.
Here is the relevant part of my kernel config, sorry for the length:
device sio0 at isa? port IO_COM1 flags 0x10 irq 4
#device sio1 at isa? disable port IO_COM2 irq 3
device sio2 at isa? port 0x100 flags 0x01105

device sio13 at isa? port 0x158 flags 0x01105
device sio14 at isa? port 0x160 flags 0x01105
device sio15 at isa? port 0x168 flags 0x01105
device sio16 at isa? port 0x170 flags 0x01105
device sio17 at isa? port 0x178 flags 0x01105 irq 3
Note I am using irq 3 for the Boca and sio1 is disabled. The
corresponding port ("com2") IS disabled on the motherboard. Also sio4
is disabled to get my 3c509 to detect properly. I know this is an odd
setup but I am convinced it is correct and it worked setup exactly
like this with the 3.0-RELEASE. I have the 3.0 disk still and I tried
it again this afternoon, just to be sure it is not a hardware problem,
and it still works fine.
Here's the bad news: The 3.0-RELEASE had an sio.c rev. 1.209 and the
current is 1.287. I have stared and stared at the diff and I don't
see any obvious problems.
Here is the relevant part of my -v dmesg (and the full one is attached
- it's too long to not compress)
