Date: Tue, 4 Dec 2012 11:40:04 +0200 (EET) From: Meelis Roos <mroos@...ux.ee> To: Linux Kernel list <linux-kernel@...r.kernel.org>, Linus Torvalds <torvalds@...ux-foundation.org> cc: Jens Axboe <axboe@...nel.dk> Subject: Regression in 3.7-rc8: block device size This is on a couple of different Sun sparc64 machines with pata_ali IDE controller. These machines work with no warnings in 3.7-rc7 and the same userspace. On 3.7-rc8, I get warning about trying to access beyond end of device: [ 65.219323] scsi0 : pata_ali [ 65.258060] scsi1 : pata_ali [ 65.296641] ata1: PATA max UDMA/66 cmd 0x1fe02010200 ctl 0x1fe02010218 bmdma 0x1fe02010220 irq 12 [ 65.413331] ata2: PATA max UDMA/66 cmd 0x1fe02010210 ctl 0x1fe02010208 bmdma 0x1fe02010228 irq 12 [ 66.136974] ata1.00: ATA-7: SAMSUNG SP1213N, TL100-30, max UDMA/100 [ 66.219314] ata1.00: 234493056 sectors, multi 0: LBA48 [ 66.647130] ata1.00: configured for UDMA/66 [ 66.702603] scsi 0:0:0:0: Direct-Access ATA SAMSUNG SP1213N TL10 PQ: 0 ANSI: 5 [ 66.972381] sd 0:0:0:0: [sda] 234493056 512-byte logical blocks: (120 GB/111 GiB) [ 67.127131] sd 0:0:0:0: [sda] Write Protect is off [ 67.190117] sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 [ 67.485709] sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA [ 67.611785] sda: sda1 sda2 sda3 sda4 sda5 [ 67.668594] sd 0:0:0:0: [sda] Attached SCSI disk [ 67.734334] EXT4-fs (sda2): couldn't mount as ext3 due to feature incompatibilities [ 67.835795] EXT4-fs (sda2): couldn't mount as ext2 due to feature incompatibilities [ 67.964315] EXT4-fs (sda2): mounted filesystem with ordered data mode.
