+Subject: [PATCH] grub_fs_probe(): dprint errors from filesystems
+
+When filesystem detection fails, all that's currently debug-logged is a
+series of messages like:
+
+    grub-core/kern/fs.c:56:fs: Detecting ntfs...
+    grub-core/kern/fs.c:76:fs: ntfs detection failed.
+
+repeated for each filesystem.  Any messages provided to grub_error() by
+the filesystem are lost, and one has to break out gdb to figure out what
+went wrong.
+
+With this change, one instead sees:
+
+    grub-core/kern/fs.c:56:fs: Detecting fat...
+    grub-core/osdep/hostdisk.c:357:hostdisk: reusing open device
+    `/path/to/device'
+    grub-core/kern/fs.c:77:fs: error: invalid modification timestamp for /.
+    grub-core/kern/fs.c:79:fs: fat detection failed.
+
+in the debug prints.
