I've not seen better options than disabling the DMA on the drive. This error usually is a drive advertising DMA support but not actually supporting it; but once in a while it's a bad cable. Thanks, I'll stick with NO DMA as I don't think it's a bad cable. Maybe add this CRD-8480B to the no-dma list ? Yup agreed; I just added it |
Description of problem: During intallation process system seems to hang (ALL is frozen); effectively it only is a loooong time out due to DMA. How reproducible: Always Steps to Reproduce: 1. mount /mnt/cdrom Actual Results: After minutes the system returns to life Expected Results: Immediate rensponse. Additional info: System is compaq deskpro (Pentium III Katmai, 450 Mhz). Upgraded to kernel-2.4.3.12.i686 but no results. with latest kernel dmesg reports these relevant informations: hdd: set_drive_speed_status: status=0x51 { DriveReady SeekComplete Error } hdd: set_drive_speed_status: error=0xb4 hdd: ATAPI 48X CD-ROM drive, 128kB Cache, DMA Uniform CD-ROM driver Revision: 3.12 hdd: timeout waiting for DMA ide_dmaproc: chipset supported ide_dma_timeout func only: 14 scanning for RockRidge behind XA attributes ISOFS: changing to secondary root hdd: timeout waiting for DMA ide_dmaproc: chipset supported ide_dma_timeout func only: 14 If I disable DMA on that device (/sbin/hdparm -d0 /dev/hdd) the problem disappears. The drive, as identified by /proc/ide/hdd/model is an CRD-8480B (maybe LG?) Question: is this - NO DMA - the best setup or is it possible to try any option to use again DMA?
