 Posted: Sat Sep 20, 2003 12:30 am Post subject: cd burning uses 100% of proc |
 |
|
Hello, I think I have gathered all pertinent data on my problem, so here it is in detail:
I am running vanilla-sources kernel 2.4.21 with all of the IDE/SCSI options enabled for scsi-emulation and IDE support. Every time I try to use either cdrecord or xcdroast to copy, read for creation of an image, or burn a CD, between 98-100% of my proc is used. Also, the burn speed jumps from 4x-19x--but never even approaches my drive's speed of 32x. The media I try this with is all speed rated up to 40x or so, so that is not an issue here. This happens every time without fail. I run a very simple FVWM setup with gkrellm as my system monitor, and use nAIM, xmms, galeon, and sylpheed on a regular basis. Even with all of these (except nAIM) turned off, the problem still occurs. I have also tried gaming-sources, under which I got the same results. As the data below will show, I have dma turned on for both the CDRW and the DVDROM and the following versions for:
cdrtools:2.01_alpha14
cdrdao: 1.1.7-r1
xcdroast: 0.98_alpha13
HDB (DVD)

hdparm results for the linux drive: (hdd)
| Code: | hdparm -tT /dev/hdd
/dev/hdd:
Timing buffer-cache reads: 128 MB in 0.63 seconds =203.17 MB/sec
Timing buffered disk reads: 64 MB in 2.66 seconds = 24.06 MB/sec

I would like to get my system to a point where burning a CD can be achieved a steady speed, more or less, and one at which my proc is not used up.
Thanks in advance for all of your help--I have spent hours trying different things I have read on here as well as discussing this with other gentoo users, so this was a last resort.
Thank you!!! |

| I think the problem has to do with the drive itself. What kind of drive is it? I've had decent brand drives that experienced the same problems (under windows however, I haven't done any burning under linux). I don't remember if I was able to fix it or not but you may want to try replacing your IDE cable. Also try connecting it to a different IDE slot if you can. I suggest putting it on the secondary master. You should hopefully see some improvement. |

maybe try appending "hdc=ide-scsi" to your kernel boot line to make sure that scsi emulation is turned on for the drive.
Then rescan devices with XCDRoast and choose the one that does NOT have ATAPI in the beginning of it's name.
I had the high cpu usage when I was burning in ATAPI mode, before I switched to scsi emulation.

| Ah, I did forget to include that information. I do have a line in my kernel boot that activates scsi emulation--and both drives are LITE-ON, quite reliable from what I read prior to buying them. Also, I made sure that xcdroast does NOT use the atapi version of the drive--that it only uses, for example device 0,1,0 rather than 0,1,0 [ATAPI] I have replaced the cable--and the only reason the drives are set up as they are, is to make it the most favorable set up for burning--I thought perhaps having the read drive and the write drive on different channels might help in the transfer rate. Also, my files drive--from which I might burn ISOs, for example, is not on the same channel as the burner or my linux harddrive. |

| Can someone please help me with this? I was able to semi-fix cdrecord when burning ISOs by using a different driver, but that still does not fix the cd-copying problem... |

If the ide-scsi emulation was enabled for that hdc driver, you'd have no /dev/hdc
Have you read the truth about cd-recording with scsi emulation? It is the best thread for it, IMO.
