[ltp] slmdm driver: closing minicom through X menu hangs kernel
Mon, 22 Dec 2003 22:58:02 -0800
I followed the instructions at:
and installed the smlink driver 1.7.10, including the PCI device ID
change mentioned in that web page.
The modem seems to work OK (just tried minicom so far, working on PPP
next) but I hit a weird problem: When I ran minicom from X and tried to
exit by accessing the File->Close Window menu option the systems locks
hard: There's no response to the mouse and keyboard, the display is
"frozen" and ctrl-alt-backspace, fn-f4, ctrl-alt-del all do nothing. I
have to press the on/off button to turn it off.
Exiting minicom using ctrl-A,X works (it also works when running minicom
from the console since the File etc. menu isn't there).
2.4.23 kernel from kernel.org, cpufreq patch (speedstep-centrino loaded)
My theory is that some ioctl that minicom calls on the modem device when
closed one particular way freezes the driver, but I don't know how to
track down what's going on. If someone else has a clue about what's
going on I'd appreciate it. Of course pointers to alternatives to the
slmdm driver, if they exist, are also welcome.
