Hi. Summary: I ended up with an unkillable jpilot process and an unloadable visor module.
With a vanilla 2.4.22, I was synchronizing my Tungsten C when I
removed it from the cradle. J-Pilot 0.99.6 said:
ReadDBList returned = -1
J-Pilot: sync PID = 3343
J-Pilot: press the hotsync button on the cradle or "kill 3343"
I killed the process, which went well, and tried to synchronize once
again.
Nothing happened. When I tried to stop the process:
Syncing on device /dev/ttyUSB1
Press the HotSync button now
****************************************
J-Pilot: sync PID = 3382
J-Pilot: press the hotsync button on the cradle or "kill 3382"
I ended up with:
[EMAIL PROTECTED] ~> ps 3382
PID TTY STAT TIME COMMAND
3382 tty1 D 0:00 jpilot
[EMAIL PROTECTED] ~> kill -9 3382
[EMAIL PROTECTED] ~> ps 3382
PID TTY STAT TIME COMMAND
3382 tty1 D 0:00 jpilot
The process cannot be killed.
Looking at my logs:

ksymoops 2.4.9 on i686 2.4.22-jibboom. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.22-jibboom/ (default)
-m /boot/System.map-2.4.22-jibboom (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.
