isdn4linux problem: "Device or ressource busy"

isdn4linux problem: "Device or ressource busy"

Post by Dmitri Barsk » Sun, 31 Dec 1899 09:00:00


I badly need help with installing isdn4linux on my good old-fashioned
P75 box.
The kernel compiles with the newest pathes without errors, the
isdn4k-utils compile as well. However, when I try to insmod or modprobe
the modules "isdn.o", it fails with the error message "insmod:
init_module: device or ressource busy ". At the same time, syslog says
"Cannot allocate device struct".
This all happens BEFORE I try to load the hisax module, which should
bother about the card itself.
I'm using RH60 ( however, SuSE61 produces the same result ) with the
2.3.5ac1 kernel ( again, it happens with every other kernel version I've
tried ). The hardware: P75, 8 Mb RAM ( ok, it's a little bit too
little...but otoh I've got a 64 Mb swap ). The isdn card itself is an
old-fashioned AVM Fritz! ( aka A1 ). No PCI, no PnP crap. Btw.: does
anyone know, which IRQ is used by that card? You cannot set it with the
jumpers, only the io address is variable... And one more question: is
there any ( non-graphical, because the box is not running X11 and I'm
configuring it with telnet ) tool to setup a dial-up isdn connection?
Something like yast but under GPL ( because I'm now using RedHat... ).
Currently I use kisdn, but it means that I have to switch to runlevel 5
each time I want to connect to internet... AND it would not run on the
P75 box - I haven't installed nor configured qt or kde there...

1. how to kill "mt" or make "/dev/rmt/..." device NOT BUSY?

Hi everybody,

I'm using an Exabyte 8mm tape drive through "/dev/rmt/0lbn" unser Solaris 2.4.

If something goes wrong with the tape during execution of "mt ..." command,
this command hangs in a state in which it can't be interrupted or killed.
The device remains busy even if I can manually eject the tape. The only
way to get the access to the tape is to reboot the system.

Is it possible to kill "mt" somehow or make the tape device NOT BUSY some
other way? Are there any timeouts defined for the "mt"/device (if so,
can they be made shorter) ?

any help will be appreciated,

regards, Michal.
