TEL_S0_8 on i4b (isdnd -v 00.70.0) with FreeBSD-3.3 seems broken !
Try this to prove it (or Please tell me what I've done wrong :-)
Please note you can try this on any system, you don't need an ISDN card,
in fact it'll be easiest to test on systems with No ISDN card in !
Apply this diff to src/sys/i386/conf/

Boot the kernel & get from dmesg (with no isdn card in):
isic0 at irq 5 maddr 0xd0000 msize 4096 flags 0x1 on isa
isic0: Error, HSCX version 15 unknown!
isic0: irq with no handler
aha0 not probed due to I/O address conflict with isic0 at 0xffffffff
or with an 8 bit card in:
isic0 at irq 5 maddr 0xd0000 msize 4096 flags 0x1 on isa
isic0: Teles S0/8 or Niccy 1008
isic0: ISAC 2085 Version V2.3 (B3) (IOM-1) (Addr=0xc00d0100)
isic0: HSCX 82525 Version A3 (AddrA=0xc00d0180, AddrB=0xc00d01c0)
adv0 not probed due to I/O address conflict with isic0 at 0xffffffff
bt0 not probed due to I/O address conflict with isic0 at 0xffffffff
aha0 not probed due to I/O address conflict with isic0 at 0xffffffff
So what's this 0xffffffff collision ? (I'll look at newer source after
fetching, but this looks like a failure needing to be reported ).
Note manual says: "Notice that this cards must not have a port value in
the config line."
I later got the revelatory "aha0 not probed" messages on an IDE-only box.
No wonder I was earlier getting panics on a scsi-only box,
PS for commiters,
man isic (& i4b-00.82.00-beta-140799.tar.gz man/isic.4) show
options "TEL_S0_8"
device isic0 at isa? iomem 0xd0000 net irq 5 flags 1 vector isicintr
options "TEL_S0_16"
device isic0 at isa? port 0xd80 iomem 0xd0000 net irq 5 flags 2 vector
but at least for FreeBSD the "vector isicintr" is obsolete, & should be removed
(but maybe it's left there for Open & NetBSD ?)
I have appended my previous post re. panics,
(for which I got zero response, I guess everyone was busy :-)

Subject: options TEL_S0_8 - changing root device to da0a - panic
Sender: owner-freebsd-isdn@FreeBSD.ORG
On hardware that previously ran fine with a 16 bit creatix card +
FreeBSD 3.2-RELEASE + TEL_S0_16 + isdnd 00.70.0,
I now see panics on boot with
FreeBSD 3.3-RELEASE + TEL_S0_8 + isdnd 00.70.0
like this
Considering FFS root f/s.
changing root device to da0s1a
changing root device to da0a
error 6: panic: cannot mount root (2)
sc0: sc_switch_scr() 1
Whether the 8 bit card is in the box or not makes no difference!
(the 16 bit card went to a faster box, the old box with 8bit is reserve box)
To isolate fault, I've also removed
mult-io (sio + flop + ide + lpt)
mitsumi-cd controller
all that is left in is the unchanged ed0 ether, 1542 aha0 scsi, & svga.
It boots properly if configured with TEL_S0_16 !
Considering FFS root f/s.
changing root device to da0s1a
[ da0s1: type 0xa5, start 0, end = 832526, size 832527 : OK]
(yes, note the absence of 2nd line "changing root device to da0a" ? )
I may have some bad combo of rootdev/curdev in /boot/* & config file
("config kernel root on wd0" or da0 etc), but that's not the real point,
something in config'ing with TEL_S0_8 rather than TEL_S0_16 triggers the
panic on boot !
First I'm going to try & repeat this on another just built machine,
(TEL_S0_8 with & without card in) & see if that panics too,
Maybe later on more modern i4b & also try to boot kernel from gdb (gulp!).
I tweaked my config a lot till I figured what was triggering the panic,
including using some silly configs, but I'm sure it is the TEL_S0_8
that's tickling it. FYI here's my config
