From mboxrd@z Thu Jan 1 00:00:00 1970 From: Richard Whitlock Subject: UDMA failure with UDMA/100 CF card, pata_pdc2027x, MPC8347 Date: Tue, 09 Sep 2008 14:38:34 +0100 Message-ID: <48C67C5A.8050006@btconnect.com> Reply-To: richw@netcomuk.co.uk Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Return-path: Received: from c2bthomr10.btconnect.com ([213.123.20.128]:23149 "EHLO c2bthomr10.btconnect.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1753899AbYIINia (ORCPT ); Tue, 9 Sep 2008 09:38:30 -0400 Sender: linux-ide-owner@vger.kernel.org List-Id: linux-ide@vger.kernel.org To: linux-ide@vger.kernel.org Having a bit of difficulty with the following: 2.6.27-rc1 pata_pdc2027x.ko MPC8347 Promise pdc20275 The following console output is produced when I try to load pata_pdc2027x. Each attempt takes several tens of seconds to fail. Loading the module takes 2 to 3 minutes. Once the module has been loaded, mounting SDA1 takes about 20 seconds, but can be accessed successfully (albeit slowly) Having throttled back to PIO4, it seems to work - but does anyone have any ideas why the exceptions in all UDMA modes? pata_pdc2027x 0000:00:0b.0: version 1.0 pata_pdc2027x 0000:00:0b.0: PLL input clock 16485 kHz scsi0 : pata_pdc2027x scsi1 : pata_pdc2027x ata1: PATA max UDMA/133 mmio m16384@0xc0100000 cmd 0xc01017c0 irq 16 ata2: PATA max UDMA/133 mmio m16384@0xc0100000 cmd 0xc01015c0 irq 16 ata1.00: CFA: LEXAR ATA FLASH CARD, 20070228, max UDMA/100 ata1.00: 7831152 sectors, multi 0: LBA ata1.00: configured for UDMA/100 scsi 0:0:0:0: Direct-Access ATA LEXAR ATA FLASH 2007 PQ: 0 ANSI: 5 sd 0:0:0:0: [sda] 7831152 512-byte hardware sectors (4010 MB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 sd 0:0:0:0: [sda] Write cache: disabled, read cache: enabled, doesn't support DPO or FUA sd 0:0:0:0: [sda] 7831152 512-byte hardware sectors (4010 MB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 sd 0:0:0:0: [sda] Write cache: disabled, read cache: enabled, doesn't support DPO or FUA sda:<3>ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen ata1.00: cmd c8/00:08:00:00:00/00:00:00:00:00/e0 tag 0 dma 4096 in res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) ata1.00: status: { DRDY } ata1: soft resetting link ata1.00: configured for UDMA/100 ata1: EH complete ata1.00: limiting speed to UDMA/66:PIO4 ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen ata1.00: cmd c8/00:08:00:00:00/00:00:00:00:00/e0 tag 0 dma 4096 in res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) ata1.00: status: { DRDY } ata1: soft resetting link ata1.00: configured for UDMA/66 ata1: EH complete ata1.00: limiting speed to UDMA/33:PIO4 ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen ata1.00: cmd c8/00:08:00:00:00/00:00:00:00:00/e0 tag 0 dma 4096 in res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) ata1.00: status: { DRDY } ata1: soft resetting link ata1.00: configured for UDMA/33 ata1: EH complete ata1.00: limiting speed to PIO4 ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen ata1.00: cmd c8/00:08:00:00:00/00:00:00:00:00/e0 tag 0 dma 4096 in res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) ata1.00: status: { DRDY } ata1: soft resetting link ata1.00: configured for PIO4 ata1: EH complete sda1 sd 0:0:0:0: [sda] Attached SCSI removable disk
