/var/log/messages errors without hdd=ide-scsi
PIO v DMA problem at a first guess but very strange indeed. Motherboard chipset is i845 (piix ICH2), whose IDE timings seem to be non-adjustable once the ATA mode is set. [How can I force a change from PIO mode 4 (mwDMA2) to PIO mode 3 (mwDMA1)? Or set the address-setup time to 120ns absolutely, like on VIA chipsets?] Workaround: boot with a CD-ROM or CD-RW [either blank or already recorded] in hdd (SONY CRX175E2). Then there are no errors reported in /var/log/messages, even without hdd=ide-scsi, and burning a CD-RW works using "cdrecord dev=/dev/hdd ..." So it looks like a device-specific problem [slow or bad SONY]. any better with the 2.6.9 update ? Hardware has changed, the problem does not occur with new hardware under kernel-2.6.9-1.6_FC2. The old hardware is unavailable for testing. Configuration is now: hdc: PLEXTOR DVDR PX-712A, ATAPI CD/DVD-ROM drive [replaces LG DVD-ROM DRD-8160B] hdd: SONY CD-RW CRX175E2, ATAPI CD/DVD-ROM drive [same as before] In addition to software updates, this could cast some doubt on the hardware behavior of the old LG DVD-ROM when used as master with a slave present. |
