I've been experiencing a repeatable kernel oops using the Handspring
Visor USB driver and the 2.4.0-test1 kernel. While I assume this
could go to the usbvisor list, since the oops appears to be coming
from usbcore, rather than usb-serial, I'm sending the info here---
feel free to point me there if I picked wrong. :)
Basically, as documented in the Visor driver documentation, the
device only shows up when the Hotsync button is pressed, and
disappears when the sync is completed. As soon as the sync completes
and the driver "disappears," I get the following kernel oops (as
translated by ksymoops):
ksymoops 2.3.4 on i686 2.4.0-test1. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.0-test1/ (default)
-m /usr/src/linux/System.map (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.
