Subject: [PATCH] ACPI / PM: Do not save/restore NVS on Sony Vaio VGN-NW130D
Date: Sun, 12 Dec 2010 21:10:42 +0100 [thread overview]
Message-ID: <201012122110.42717.rjw@sisk.pl> (raw)
From: Rafael J. Wysocki <rjw@sisk.pl>
The saving of the NVS memory area during suspend and restoring it
during resume causes problems to appear on Sony Vaio VGN-NW130D, so
blacklist that machine to avoid those problems.
