It's likely the rsyslogd is unable to write the crash into files. What does happen if you're on text console when you plug it in? Please do this: <Ctrl><Alt>F1 log in as root echo 8 > /proc/sys/kernel/printk resizecons -lines 50 plug the adapter in At this point you are likely to see a traceback which can be taken with a camera (capturing it with netconsole would be even better, but that requires reading Documentation/networking/netconsole.txt which is confusing and out of date, then installing netcat (which RPM is named "nc" in Fedora)).

Screen showing output immediately after plugging in usb adapter
Following #1 this is the screen a few seconds after logging in to KDE, then
switching to an alternative console and logging in as root, and setting up to
print diagnostics. After 20 seconds more text appears on the screen and the
next image shows the further lines output.

printk captured via netconsole (equivalent to images above)
I managed to get a capture on a second machine on the same network using
netconsole. Here is the capture.
A patch to correct this should be available in kernel-2.6.25-0.234.rc9.git1.fc9 or later...probably available tomorrow or the next day...FYI! :-) Thanks John - will test this later today or tomorrow.... and report back. kernel-2.6.25-0.234.rc9.git1.fc9 resolves this bug and wireless now works nicely again. This bug can now be closed. Thanks for working on this. |
