OK same procedure as before except that i connected the nullmodem to
another machine.
And again a similar oops as the last one. And perhaps another hint which
may help you: I got several of the following line while sending to
ttyUSB0:
ftdi_sio.c: write request of 0 bytes
ksymoops 2.4.6 on i686 2.4.20-w4l. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.20-w4l/ (default)
-m /boot/System.map-2.4.20-w4l (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
