This bug occurred on a Dell Studio XPS. It also occurred on an Alienware machine - both fairly old, perhaps 8 years. The Alienware machine was at the same software level as the Dell Studio XPS. On the Alienware machine, occasionally after some time (say five minutes). With an encrypted drive, the drive might appear (or not), but access was iffy - with the system asking multiple times for the password, but almost never granting access. When access was granted, access to the files was eventually terminated - the directory window in Nautilus eventually showing no files.
