[Mageia-dev] HAL woes

Mon Jul 30 14:00:42 CEST 2012

On a pre-/usr cauldron which has intentionally not been updated, wine 
+apps have suddenly stopped being able to "see" mounted DVDs.
+
+Checking syslog immediately after ejecting and reloading the disk, I find:

+*******************************************************************************
+
+Based on observation, the stuff timestamped 10:50:50 is the result of 
+ejecting the disk, and the last few lines timestamped 10:50:54 are the 
+result of reloading it, with the intervening 4 seconds consumed by 
+reading the disk headers and such.
+
+I seem to remember here that nothing is supposed to be using HAL, so 
+it's puzzling as to why systemd would be trying to start it in response 
+to the load.  It's equally puzzling as to why this should suddenly 
+affect wine, when nothing's been upgraded (this worked 2 or 3 days ago).
+
+The disk is correctly mounted and identified by KDE, and is usable by 
+k3b and command-line utilities.  k3b also detects the load event, and 
+switches its GUI prompt from "insert a disk" to the actual label.
+
+Is wine still hal-dependent when it ought not to be ?
