Hi, i don't know what is happening.
I burned a disk with the same kernel config two days ago, and remerged my burning programs(update).
Well now i can't burn anymore.
dmesg shows the following error message:
| Code: |
scsi: unknown opcode 0x01
hdd: irq timeout: status=0xd0 { Busy }
ide: failed opcode was: unknown
hdd: DMA disabled
hdd: ATAPI reset complete
hdd: irq timeout: status=0xd0 { Busy }
ide: failed opcode was: unknown
hdd: ATAPI reset complete
hdd: irq timeout: status=0xd0 { Busy }
ide: failed opcode was: unknown
hdd: status timeout: status=0xd0 { Busy }
ide: failed opcode was: unknown
hdd: drive not ready for command
hdd: ATAPI reset complete
|
cdrdao:
| Code: |
Starting write at speed 12...
Pausing 10 seconds - hit CTRL-C to abort.
Process can be aborted with QUIT signal (usually CTRL-\).
WARNING: No super user permission to setup real time scheduling.
Turning BURN-Proof on
Executing power calibration...
ERROR: Power calibration failed.
ERROR: Use option --force to ignore this error.
|
So, what can i do now?
Does anyone have an idea?
Thank you for your help.

that should turn your dma back on

Thank you for your great help 
The command #hdparm -d1 /dev/hdd
Helped me.
Could you please tell me what it does and why I have to run it?

for a full explenation go to http://gentoo-wiki.com/HOWTO_Use_hdparm_to_improve_IDE_device_performance
but hdparm modifies your hd and cd/dvdrom drives
-d1 option turns dma on -d0 turns it off
if you are asking what dma is it basically bypasses the processor when writing to memory from hd or cdrom or vice versa
if everytime you reboot the computer the computer turns off dma you can add to the bottom of /etc/conf.d/hdparm then do | Code: | | rc-update add hdparm boot |
