Hi list, Recently put 8.1 on a used PIII 1Ghz box and have just had a crash. I noticed the following in my /var/log/messages file: Aug 5 10:58:00 langly kernel: hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error } Aug 5 10:58:00 langly kernel: hdb: dma_intr: error=0x40 { UncorrectableError }, LBAsect=18041498, sector=10490808 Aug 5 10:58:00 langly kernel: end_request: I/O error, dev 03:46 (hdb), sector 10490808 Aug 5 10:58:06 langly kernel: hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error } Aug 5 10:58:06 langly kernel: hdb: dma_intr: error=0x40 { UncorrectableError }, LBAsect=18041498, sector=10490816 Aug 5 10:58:06 langly kernel: end_request: I/O error, dev 03:46 (hdb), sector 10490816 Aug 5 10:58:12 langly kernel: hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error } Aug 5 10:58:12 langly kernel: hdb: dma_intr: error=0x40 { UncorrectableError }, LBAsect=18041498, sector=10490824 Aug 5 10:58:12 langly kernel: end_request: I/O error, dev 03:46 (hdb), sector 10490824 Aug 5 10:58:17 langly kernel: hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error } Aug 5 10:58:17 langly kernel: hdb: dma_intr: error=0x40 { UncorrectableError }, LBAsect=18041498, sector=10490832 Aug 5 10:58:17 langly kernel: end_request: I/O error, dev 03:46 (hdb), sector 10490832 Aug 5 10:58:23 langly kernel: hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error } Aug 5 10:58:23 langly kernel: hdb: dma_intr: error=0x40 { UncorrectableError }, LBAsect=18041498, sector=10490840 Aug 5 10:58:23 langly kernel: end_request: I/O error, dev 03:46 (hdb), sector 10490840 Aug 5 10:58:29 langly kernel: hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error } Aug 5 10:58:29 langly kernel: hdb: dma_intr: error=0x40 { UncorrectableError }, LBAsect=18041498, sector=10490848 Aug 5 10:58:29 langly kernel: end_request: I/O error, dev 03:46 (hdb), sector 10490848 Aug 5 10:58:34 langly kernel: hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error } Aug 5 10:58:34 langly kernel: hdb: dma_intr: error=0x40 { UncorrectableError }, LBAsect=18041498, sector=10490856 Aug 5 10:58:34 langly kernel: end_request: I/O error, dev 03:46 (hdb), sector 10490856 Aug 5 10:58:40 langly kernel: hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error } Aug 5 10:58:40 langly kernel: hdb: dma_intr: error=0x40 { UncorrectableError }, LBAsect=18041498, sector=10490864 Aug 5 10:58:40 langly kernel: end_request: I/O error, dev 03:46 (hdb), sector 10490864 Aug 5 10:58:45 langly kernel: hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error } Aug 5 10:58:45 langly kernel: hdb: dma_intr: error=0x40 { UncorrectableError }, LBAsect=18041498, sector=10490872 Aug 5 10:58:45 langly kernel: end_request: I/O error, dev 03:46 (hdb), sector 10490872 Aug 5 10:58:51 langly kernel: hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error } Aug 5 10:59:04 langly kernel: hdb: dma_intr: error=0x40 { UncorrectableError }, LBAsect=18041498, sector=10490880 Aug 5 10:59:04 langly kernel: end_request: I/O error, dev 03:46 (hdb), sector 10490880 Aug 5 10:59:04 langly kernel: hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error } Aug 5 10:59:04 langly kernel: hdb: dma_intr: error=0x40 { UncorrectableError }, LBAsect=18041501, sector=10490888 Aug 5 10:59:04 langly kernel: end_request: I/O error, dev 03:46 (hdb), sector 10490888 Aug 5 10:59:04 langly kernel: hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error } Aug 5 10:59:04 langly kernel: hdb: dma_intr: error=0x40 { UncorrectableError }, LBAsect=18041509, sector=10490896 Aug 5 10:59:04 langly kernel: end_request: I/O error, dev 03:46 (hdb), sector 10490896 I notice this happening since August 2nd about every 5 minutes, the log goes back to July 23. I also notice this every now and then: Aug 5 11:16:58 langly kernel: cdrom: open failed. Finally, I just realized that on bootup, that this drive is configured as IDE Primary Slave not Master (this is how it was when I got it). I have a Secondary Master CDROM drive. Could this be causing problems? Here is output from hdparm: langly /var/log# hdparm -i /dev/hdb /dev/hdb: Model=WDC WD300AB-00BVA0, FwRev=21.01H21, SerialNo=WD-WMA7H1415190 Config={ HardSect NotMFM HdSw>15uSec SpinMotCtl Fixed DTR>5Mbs FmtGapReq } RawCHS=16383/16/63, TrkSize=57600, SectSize=600, ECCbytes=40 BuffType=DualPortCache, BuffSize=2048kB, MaxMultSect=16, MultSect=16 CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=58633344 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 UDMA modes: udma0 udma1 udma2 udma3 udma4 *udma5 AdvancedPM=no WriteCache=enabled Drive conforms to: device does not report version: 1 2 3 4 5 Any help would be appreciated.
