BadCRC indicates a cable problem ;( While I can of course not entirely rule out a hardware problem, I don't have a reasonable explanation why under 2.4.9, this error doesnt happen.I have even exchanged the cable, to no avail. Mind: This is only UDMA/33, it should not even need the 80 wire cable... Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/ |
Description of Problem: After updating to the 2.4.18-17.7.x Errata kernel, I see several messages like this in the syslog: Oct 21 11:16:32 station159 kernel: hdc: dma_intr: error=0x84 { DriveStatusError BadCRC } Oct 21 11:16:32 station159 kernel: hdc: dma_intr: status=0x51 { DriveReady SeekComplete Error } Switching back to the old 2.4.9-34 kernel and everything looks fine. I thus assume my Hardware to be OK (yes, its a 80pin UDMA cable) Version-Release number of selected component (if applicable): 2.4.18-17.7.x How Reproducible: Almost always Steps to Reproduce: 1. Reboot machine using 2.4.18-17.7 kernel 2. 3. Actual Results: IDE DMA error messages as above Expected Results: No error messages, as in 2.4.9-34 Additional Information: Used hardware (as taken running 2.4.9-34) [root@station159 log]# /sbin/hdparm -i /dev/hdc /dev/hdc: Model=QUANTUM FIREBALLlct08 17, FwRev=A05.0X00, SerialNo=394935025980 Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs } RawCHS=16383/16/63, TrkSize=32256, SectSize=21298, ECCbytes=4 BuffType=DualPortCache, BuffSize=418kB, MaxMultSect=16, MultSect=16 CurCHS=16383/16/63, CurSects=-66060037, LBA=yes, LBAsects=33906432 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 udma0 udma1 *udma2 AdvancedPM=no Drive Supports : ATA/ATAPI-4 T13 1153D revision 15 : ATA-1 ATA-2 ATA-3 ATA-4 lspci -v: 00:00.0 Host bridge: Advanced Micro Devices [AMD] AMD-751 [Irongate] System Controller (rev 25) Flags: bus master, medium devsel, latency 64 Memory at e8000000 (32-bit, prefetchable) [size=32M] Memory at ebbff000 (32-bit, prefetchable) [size=4K] I/O ports at dc00 [disabled] [size=4] Capabilities: [a0] AGP version 1.0 00:01.0 PCI bridge: Advanced Micro Devices [AMD] AMD-751 [Irongate] AGP Bridge (rev 01) (prog-if 00 [Normal decode]) Flags: bus master, 66Mhz, medium devsel, latency 64 Bus: primary=00, secondary=01, subordinate=01, sec-latency=64 I/O behind bridge: 0000a000-0000afff Memory behind bridge: ebc00000-edcfffff Prefetchable memory behind bridge: e3a00000-e7afffff [...] 00:07.0 ISA bridge: VIA Technologies, Inc.
