IO-APIC + IDE (PDC20262) => lost interrupts and filesystem corruption
Last modified: 2008-08-01 12:22:51 EDT
From Bugzilla Helper: User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.3-2.14.10 i586) Description of problem: I have discovered that if I plug IDE drives into both channels of the Promise Ultra66 controller in my DEC Celebris 5133/DP (dual Pentium 133 machine) and access drives on both channels at the same time, *bad things* can happen: lost interrupts leading to filesystem corruption. I discovered the problem initially when I plugged an ATAPI CDRW drive into the second IDE channel and attempted to burn a disk using cdrecord. That caused lost interrupts, and kernel messages looking roughly as follows: kernel: ide_dmaproc: chipset supported ide_dma_lostirq func only: 13 kernel: hdf: lost interrupt kernel: ide_dmaproc: chipset supported ide_dma_lostirq func only: 13 kernel: hdg: lost interrupt kernel: hdf: timeout waiting for DMA kernel: ide_dmaproc: chipset supported ide_dma_timeout func only: 14 hdf: irq timeout: status=0x50 { DriveReady SeekComplete } I can't give you the exact errors, because shortly thereafter the /var filesystem got trashed and the log files were too smashed for fsck to be able to recover them. After replacing the CDRW with a hard drive, I got similar errors with a large file copy (CD-ROM image) leaving me to assume that the problem was not drive related. Updating to the most recent kernel from Red Hat's Rawhide distribution did not fix the problem. I tried rebooting in uniprocessor mode, but continued to see problems with lost interrupts. Then, on a hunch, I tried booting in uniprocessor mode with the ``noapic'' option, and the problem of ``lost interrupts'' seems to have vanished, allowing me to use my CD-RW drive to create disks. That said, one attempt to burn a CD at 8x speed produced the following error: kernel: ide-scsi: CoD != 0 in idescsi_pc_intr kernel: hdg: ATAPI reset complete kernel: hdg: status error: status=0x58 { DriveReady SeekComplete DataRequest } kernel: hdg: drive not ready for command I've enclosed some information about the machine. If you need more details, please let me know. M.E.O. How reproducible: Always Steps to Reproduce: 1.Connect drives to both channels 2.Boot without disabling the IO-APIC 3.Copy data between drives on the two channels Actual Results: lost interrupts, corrupted filesystems Expected Results: normal data transfer between drives Additional info: Information about my machine linux% uname -a Linux tenby 2.4.3-2.14.10 #1 Mon Apr 30 19:26:24 EDT 2001 i586 unknown linux% lspci 00:00.0 Host bridge: Intel Corporation 82434LX [Mercury/Neptune] (rev 11) 00:01.0 SCSI storage controller: Symbios Logic Inc.

Quick question: Are you using the special 80 ribbon cables for the promise controller ?
The two drives on the primary channel use the 80-wire cable, but the drive on the secondary channel is using a 40-wire cable. My understanding was that the ATAPI CDRW (and the old 1GB drive I also tested on that channel) drive dose not support transfer rates faster than Ultra/33 performance, so it was fine to use a 40-wire cable in that case. I'd be happy to buy and try an 80-wire cable for that channel, but I'm not sure that it would change things.
To get things clear: you never saw problems while copying stuff from disk 0 to disk 1 or other way around (I mean, both disks on the first channel), just from second-to-first channel ?
Other question: does it happen if you disable IDE on the device in question? (eg "hdparm -d0 /dev/hdf")
I've been using the two drives on the primary channel pretty heavily (moving huge files between them) for several months, without seeing any problems. Prior to installing RH 7.1, I ran my own custom kernel which had the backported IDE patches so that I could use the Promise controller. To answer your other question, I tried turning off DMA (with ``hdparm -d0'') on the drives, but it didn't help. The lost interrupt problem persisted. FWIW, I installed another OS just to double-check my hardware configuration, and everything appears to work fine there. That, combined with the fact that turning off the IO-APIC and SMP seems to fix the problem in Linux leads me to believe that it is a software rather than hardware problem.
What version of the Promise bios is this ?
It runs the 2.0 BIOS, which is the latest one available from Promise. (I flash upgraded it shortly after gettting the card).
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/
