Subject: Host protected area on suspend/resume
Date: Tue, 12 Jul 2005 12:30:44 +0100 [thread overview]
Message-ID: <20050712113044.GA8744@srcf.ucam.org> (raw)
On boot, Linux will attempt to disable the host protected area on a
disk. After a suspend/resume cycle, the BIOS may reenable it (seen on a
Thinkpad T40 and R40). As a result, the kernel is now unable to access
the HPA.
Is there any issue with just adding a call to idedisk_check_hpa() in the
IDE resume code?
