As a matter of fact it runs quite smoothly on my machines. 2.6.25-rc1-git1 if you are using IDE. however it may still have this problem if (ireason == 0) { write = 1; xferfunc = HWIF(drive)->atapi_output_bytes; } else if (ireason == 2 || (ireason == 1 && (blk_fs_request(rq) || blk_pc_request(rq)))) { we problably need to call ide_cd_check_ireason() also for REQ_TYPE_ATA_PC requests and remove (blk_fs_request(rq) || blk_pc_request(rq) here write = 0; xferfunc = HWIF(drive)->atapi_input_bytes; } else { printk(KERN_ERR "%s: %s: The drive " "appears confused (ireason = 0x%02x). " "Trying to recover by ending request.\n", drive->name, __FUNCTION__, ireason); goto end_request; } Bart - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
