A crash of io-usb has been observed upon the insertion and removal of a
certain USB memory stick. This crash occurred using the GA 6.4.1 OS and
drivers.
The root cause was identified as a very hard to trigger (timing
dependent) bug in io-usb. The crash occurred during device removal when
looking up the device address in the device table. The devices address
is temporarily set to 0 when re-assigning the devices address. If
setting the address fails, the original device address was not being
properly restored, so future look-ups into the device table were getting
the wrong address (0) leading to the crash.
This issue is documented and has been resolved in PR#75719. This fix will be in 6.5.0 and future GA releases.
