I'm not sure but the error may be related to KDE. It happens only on PC's that use KDE and 11.0, others are unaffected. *** This bug has been marked as a duplicate of bug 210316 *** |
I get a kernel panic when moving files from phone to HDD. It happens after the upgrade from 10.3-RELEASE to 11.0-RC1. Seems to be related to VFS fixes which were committed recently. Unfortunately, I didn't use 11.0 before those fixes, so I can't say for sure.
