From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3b) Gecko/20030211 Description of problem: I have two Maxtor 6Y080L0 ide drives connected to a VIA vt8235. Both drives are cofigured as primary on the two channels. (hda,hdc) They are configured as a software raid1 device. This are the errors I see in de messages file... what does it mean? kernel: hda: dma_timer_expiry: dma status == 0x21 kernel: hda: timeout waiting for DMA kernel: hda: timeout waiting for DMA kernel: hda: (__ide_dma_test_irq) called while not waiting kernel: hda: status error: status=0x58 { DriveReady SeekComplete DataRequest } kernel: hda: drive not ready for command kernel: blk: queue c03be900, I/O limit 4095Mb (mask 0xffffffff) Version-Release number of selected component (if applicable): 2.4.20-8 How reproducible: Always Steps to Reproduce: 1. startup linux 2. watch the /var/log/messages file 3. Actual Results: see the errors mentioned at the Description Expected Results: No IDE erros Additional info:
I have the exact same error, except dma status == 0x20 I have one Maxtor, one Quantum IDE drives. Both drives are cofigured as primary on the two channels. (hda,hdc) There are two software RAID 1 devices split across the two drives. DMA is on, would turning it off help?
A command timed out - it may be a lost IRQ, it may be recalibration/recovery delays. With current IDE code its not a problem and we correctly retry it and recover. Old SMP code was buggy and could hang here in specific cases So the trace is the IDE equivalent of "Hello ?" "Hello ?" "Ah there you are"
The error mentioned above caused my system to stop responding after installing some (redhat 9 updates) bigger rpms. Reinstalled system and tried the rpm updates again, with the same result. After a reboot the ide error was the last message in /var/log/messages Changed to two IBM IC35L080AVVA07 drives. Now one drive gives the same error as above.. the other works without errors. The drive that gives the error can not be set to DMA mode.. with the command 'hdparm -d1 /dev/hda' I'm getting the same error messages. Used the IBM harddisk test software to find out if it could find a problem. But both drives just passed all tests. http://www.hgst.com/hdd/support/download.htm Drive Fitness Test and Feature Tool. Jus some additional motherboard info: DFI AD77 infinity with a kt400 chipset.
After replacing the harddisks 1by1, I have found working combinations: One of the IBM IC35L080AVVA07 had one connection pin that was half the lenght it should be, so it just did not make any contact. Strangly enough the IBM test software did not find any problem with te drive. After replacing this drive all worked fine. Also one of the maxtor drives seemed to have a problem. The problem only occoured in a software raid setup when copying large files. Standalone the problem could not be reproduced. The maxtor test did not find anything. After replacing this drive all worked fine.
