2.6.13 was released on 28 Aug. almost 5 months ago, could you give a try to 2.6.15 to se if the problem is still there? Also, IDE maintainers will probably need to know more things about your system (ie: lspci output, full dmesg etc) (Oh sorry I saw you were asked in the lkml to fill in this bug I though you were a "typical bug reporter") Yes, please retest with 2.6.15. I've tested with 2.6.15 and still see the same behaviour. In addition, DMA is left off even if keepsettings=1 I have the same problem. I'm using 2.6.17.13. This is my drive: /dev/hdd: ATAPI CD-ROM, with removable media Model Number: LITE-ON DVDRW SOHW-1633S Serial Number: Firmware Revision: BS0S Standards: Used: ATAPI for CD-ROMs, SFF-8020i, r2.5 Supported: CD-ROM ATAPI-2 Configuration: DRQ response: 50us. Packet size: 12 bytes Capabilities: LBA, IORDY(cannot be disabled) DMA: mdma0 mdma1 mdma2 udma0 udma1 *udma2 udma3 udma4 Cycle time: min=120ns recommended=120ns PIO: pio0 pio1 pio2 pio3 pio4 Cycle time: no flow control=227ns IORDY flow control=120ns Hi, Please retest with some newer kernel, i.e. 2.6.22 or 2.6.23-rc1 (2.6.17 was released on 18-Jun-2006 - this is more than year ago). PS Re-assigning the bug to ide-cd Maintainer. Please reopen this bug if it's still present with kernel 2.6.22. |
