内核的这些提示是什么意思： drive_cmd: error=0x04

schoolwind

hdb: drive_cmd: status=0x51 { DriveReady SeekComplete Error }
hdb: drive_cmd: error=0x04 { AbortedCommand }
ide: failed opcode was: 0xe5
hdb: drive_cmd: status=0x51 { DriveReady SeekComplete Error }
hdb: drive_cmd: error=0x04 { AbortedCommand }
ide: failed opcode was: 0x98
hdb: drive_cmd: status=0x51 { DriveReady SeekComplete Error }
hdb: drive_cmd: error=0x04 { AbortedCommand }
ide: failed opcode was: 0xb0

奇怪的是，系统启动完毕，运行dmesg的结果没有这些提示，然后运行startx 后再运行dmesg的最后几行出现如上错误，之前重新编译过一次内核。。。hdb为vcddvd 刻录机
