IDE bug in 2.4.2-ac12?
Hello guys,
I hope you've read my posting "DMA problem with ZIP drive and VIA VT82C598MVP
/ VT82C586B chip" (why does anybody answer?).
I now tried the 2.4.2-ac12 kernel including the latest VIA 82c586b driver
(version 3.21), but the effects were almost the same:
- just when the kernel tried to access to the hard disk during boot, DMA
errors were occured
- "hdparm /dev/hda" displayed 9 MB per second (and not 11 MB like without ZIP)
- /proc/ide/via reported 16 MB transfer rate (and not 33MB like without ZIP
drive)
- Kernel 2.4.2-ac12 reports a "ide-floppy: hdd: I/O error, pc = 5a, key = 5,
asc = 24, ascq = 0" error, 2.4.2 doesn't
My IDE configuration is:
/dev/hda: Hard disk => Primary IDE controller
/dev/hdc CD-ROM => Secondary IDE controller
/dev/hdd: ZIP => Secondary IDE controller
Could you please tell me whether it's a bug or a feature?
I'm really waiting for your answer - else I might get crazy with this problem
:-((
I attached both dmesg and /proc/ide/via, and my old posting.

IDE bug in 2.4.2-ac12?
Hello guys,
I hope you've read my posting "DMA problem with ZIP drive and VIA VT82C598MVP
/ VT82C586B chip" (why does anybody answer?).
I now tried the 2.4.2-ac12 kernel including the latest VIA 82c586b driver
(version 3.21), but the effects were almost the same:
- just when the kernel tried to access to the hard disk during boot, DMA
errors were occured
- "hdparm /dev/hda" displayed 9 MB per second (and not 11 MB like without ZIP)
- /proc/ide/via reported 16 MB transfer rate (and not 33MB like without ZIP
drive)
- Kernel 2.4.2-ac12 reports a "ide-floppy: hdd: I/O error, pc = 5a, key = 5,
asc = 24, ascq = 0" error, 2.4.2 doesn't
My IDE configuration is:
/dev/hda: Hard disk = Primary IDE controller
/dev/hdc CD-ROM = Secondary IDE controller
/dev/hdd: ZIP = Secondary IDE controller
Could you please tell me whether it's a bug or a feature?
I'm really waiting for your answer - else I might get crazy with this problem
:-((
I attached both dmesg and /proc/ide/via, and my old posting.

OK. The ZIP drive can not handle uDMA, so it's normal for the secondary controller to drop back. In my opinion, the primary controller should stay at uDMA speed, but it is PC hardware so it is perfectly possible there is something cheap that locks them together. I will bring up ac-12 and check the error message... I'm really waiting for your answer - else I might get crazy with this problem :-(( I attached both dmesg and /proc/ide/via, and my old posting. cu Konrad -- Paul Bristow http://paulbristow.net/linux/idefloppy.html Linux ide-floppy maintainer - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
