Message-ID: <430B48A5.4040702@hiramoto.org> (raw)
[-- Attachment #1: Type: text/plain, Size: 12116 bytes --]
Hi, i get this a lot now when doing: "rmmod cp2101 io_edgeport "
I try and do the rmmod, because i loose comunications on the USB to
RS-232 adapters.
Not sure if i did the ksymoops correctly but here it is:
# ./ksymoops
ksymoops 2.4.9 on i686 2.6.12-gentoo-r9. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.6.12-gentoo-r9/ (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.
Error (regular_file): read_ksyms stat /proc/ksyms failed
./ksymoops: No such file or directory
No modules in ksyms, skipping objects
No ksyms, skipping lsmod
