Hello, I found this is a regression compared with an older kernel. I have tested the same setup with the Freescale LTIB BSP 2008-06-27 BSP kernel*, keeping the user space and hardware setup exactly identical. Under that kernel, no errors occur. Also I found the error only occurs during *reading* the SSD disk under Linux 2.6.30-rc6, writing seems unaffected. As the same Freescale SATA controller IP is used in the new 8536E processor (and others), I would like to help to solve this issue before trying 8536E hardware. Regards, Leon. * http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MPC8315E&nodeId=0162468rH3bTdGJk191439&fpsp=1&tab=Design_Tools_Tab# Split out patches available from http://www.bitshrine.org/gpp/ On Tue, Jun 9, 2009 at 11:26 AM, Leon Woestenberg<leon.woestenberg@xxxxxxxxx> wrote: > Adding the sata_fsl.c developers to the recipients: > > On Mon, Jun 8, 2009 at 4:59 PM, Leon > Woestenberg<leon.woestenberg@xxxxxxxxx> wrote: >> Hello, >> >> using 2.6.30-rc6, I get the following problems when I read from a SSD >> disk, connected to the >> 3.0 Gb SATA controller of the MPC8315E SoC rev 1.0 running Linux 2.6.30-rc6. >> >> Below see the output from two dd read runs. >> >> The disk behaves fine on a x86 box. >> >> What I can do to (help) pin-point the problem? >> >> Regards, >> >> Leon. >> >> >> root@mpc8315e-rdb:~# dd if=/dev/sda of=/dev/null bs=4k >> ata2: exception Emask 0x10 SAct 0x0 SErr 0x0 action 0x2 frozen >> ata2.00: cmd c8/00:3e:1e:e0:01/00:00:00:00:00/e0 tag 0 dma 31744 in >> res 50/00:3e:e0:df:01/00:00:00:00:00/e0 Emask 0x1 (device error) >> ata2.00: status: { DRDY } >> ata2: hard resetting link >> ata2: Signature Update detected @ 3528 msecs >> ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 300) >> ata2.00: configured for UDMA/133 >> sd 1:0:0:0: [sda] Result: hostbyte=0x00 driverbyte=0x08 >> sd 1:0:0:0: [sda] Sense Key : 0xb [current] [descriptor] >> Descriptor sense data with sense descriptors (in hex): >> 72 0b 00 00 00 00 00 0c 00 0a 80 00 00 00 00 00 >> 00 01 df e0 >> sd 1:0:0:0: [sda] ASC=0x0 ASCQ=0x0 >> end_request: I/O error, dev sda, sector 122910 >> __ratelimit: 52 callbacks suppressed >> Buffer I/O error on device sda, logical block 122910 >> Buffer I/O error on device sda, logical block 122911 >> Buffer I/O error on device sda, logical block 122912 >> Buffer I/O error on device sda, logical block 122913 >> Buffer I/O error on device sda, logical block 122914 >> Buffer I/O error on device sda, logical block 122915 >> Buffer I/O error on device sda, logical block 122916 >> Buffer I/O error on device sda, logical block 122917 >> Buffer I/O error on device sda, logical block 122918 >> Buffer I/O error on device sda, logical block 122919 >> ata2: EH complete >> dd: /dev/sda: Input/output error >> >> >> root@mpc8315e-rdb:~# dd if=/dev/sda of=/dev/null bs=4k >> ata2: exception Emask 0x10 SAct 0x0 SErr 0x0 action 0x2 frozen >> ata2.00: cmd c8/00:32:9a:6e:00/00:00:00:00:00/e0 tag 0 dma 25600 in >> res 50/00:3e:5c:6e:00/00:00:00:00:00/e0 Emask 0x1 (device error) >> ata2.00: status: { DRDY } >> ata2: hard resetting link >> ata2: Signature Update detected @ 3528 msecs >> ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 300) >> ata2.00: configured for UDMA/133 >> sd 1:0:0:0: [sda] Result: hostbyte=0x00 driverbyte=0x08 >> sd 1:0:0:0: [sda] Sense Key : 0xb [current] [descriptor] >> Descriptor sense data with sense descriptors (in hex): >> 72 0b 00 00 00 00 00 0c 00 0a 80 00 00 00 00 00 >> 00 00 6e 5c >> sd 1:0:0:0: [sda] ASC=0x0 ASCQ=0x0 >> end_request: I/O error, dev sda, sector 28314 >> __ratelimit: 52 callbacks suppressed >> Buffer I/O error on device sda, logical block 28314 >> Buffer I/O error on device sda, logical block 28315 >> Buffer I/O error on device sda, logical block 28316 >> Buffer I/O error on device sda, logical block 28317 >> Buffer I/O error on device sda, logical block 28318 >> Buffer I/O error on device sda, logical block 28319 >> Buffer I/O error on device sda, logical block 28320 >> Buffer I/O error on device sda, logical block 28321 >> Buffer I/O error on device sda, logical block 28322 >> Buffer I/O error on device sda, logical block 28323 >> ata2: EH complete >> dd: /dev/sda: Input/output error >> >> >> root@mpc8315e-rdb:~# uname -a >> Linux mpc8315e-rdb 2.6.30-rc6 #1 Mon Jun 8 15:54:00 CEST 2009 ppc unknown >> >> root@mpc8315e-rdb:~# hdparm -i /dev/sda >> >> /dev/sda: >> >> Model=Solidata X SSD , FwRev=0955 , SerialNo=<...> >> Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs } >> RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=0 >> BuffType=unknown, BuffSize=0kB, MaxMultSect=128, MultSect=?1? >> CurCHS=16383/16/63, CurSects=16514064, LBA=no >> IORDY=no, tPIO={min:240,w/IORDY:120} >> PIO modes: pio0 pio3 pio4 >> UDMA modes: udma0 udma1 udma2 udma3 udma4 udma5 >> AdvancedPM=yes: disabled (255) WriteCache=disabled >> Drive conforms to: Unspecified: ATA/ATAPI-4 ATA/ATAPI-5 ATA/ATAPI-6 >> ATA/ATAPI-7 >> >> * signifies the current active mode >> >> >> >> -- >> Leon >> > > > > -- > Leon > -- Leon -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
