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.
