2013-04-25T19:25:32Z

commit b55f84e2d527182e7c611d466cd0bb6ddce201de upstream. There is a quirk patch 5e5a4f5d5a08c9c504fe956391ac3dae2c66556d "ata_piix: make DVD Drive recognisable on systems with Intel Sandybridge chipsets(v2)" fixing the 4 ports IDE controller 32bit PIO mode. We've hit a problem with DVD not recognized on Haswell Desktop platform which includes Lynx Point 2-port SATA controller. This quirk patch disables 32bit PIO on this controller in IDE mode. v2: Change spelling error in statememnt pointed by Sergei Shtylyov. v3: Change comment statememnt and spliting line over 80 characters pointed by Libor Pechacek and also rebase the patch against 3.8-rc7 kernel.

libata: Set max sector to 65535 for Slimtype DVD A DS8A8SH drive

2013-04-25T19:25:32Z

commit a32450e127fc6e5ca6d958ceb3cfea4d30a00846 upstream. The Slimtype DVD A DS8A8SH drive locks up when max sector is smaller than 65535, and the blow backtrace is observed on locking up: INFO: task flush-8:32:1130 blocked for more than 120 seconds. "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. flush-8:32 D ffffffff8180cf60 0 1130 2 0x00000000 ffff880273aef618 0000000000000046 0000000000000005 ffff880273aee000 ffff880273aee000 ffff880273aeffd8 ffff880273aee010 ffff880273aee000 ffff880273aeffd8 ffff880273aee000 ffff88026e842ea0 ffff880274a10000 Call Trace: [] schedule+0x5d/0x70 [] io_schedule+0x8c/0xd0 [] get_request+0x731/0x7d0 [] ? cfq_allow_merge+0x50/0x90 [] ? wake_up_bit+0x40/0x40 [] ? bio_attempt_back_merge+0x33/0x110 [] blk_queue_bio+0x23a/0x3f0 [] generic_make_request+0xc6/0x120 [] submit_bio+0x138/0x160 [] ? bio_alloc_bioset+0x96/0x120 [] submit_bh+0x1f1/0x220 [] __block_write_full_page+0x228/0x340 [] ? attach_nobh_buffers+0xc0/0xc0 [] ?
