Reproducible: Always Steps to Reproduce: 1.Starting linux.... 2. 3. Actual Results: Too much lines in /var/log/messages... The CD Writer seems usable (I've only test reading for now) Probably something wrong in the driver ?
Doug, can you please analyze this?
This is something Gerard will probably have to look at. Basically, the driver is renegotiating the transfer rate with the CD-ROM an inordinately large number of times, and it is logging those negotiations. Normally, those aren't logged, so I'm not sure what's up with that. I'll look into the kernel config files to see if there is anything in there that could be causing this as well. Nothing in the config files looked like it would cause this to me...time to email Gerard...
Hi Tried to burn two cd of wolfverine with the burner attached on my tekram just seem to work but doing after burning md5sum /dev/cdrom on the CDs give me bad results.... I will try to install RH7 again and make a new try to see if it works better with kernel 2.2... PS : My Burner is a TEAC CD 58s Regards JYL
Just want to add that my Motherboard is a k7v with an Athlon.... because I know that a lot of bug seems to be linked to the VIA chip... Just my 2 cents
I've got confirmation that the problem with the log files was simply that a debug flag was turned on in the driver. The reason for renegotiating every two seconds is likely magicdev or some other program checking the CD-ROM to see if it has a CD in it every two seconds, and the check resulting in a CHECK_CONDITION return from the CD-ROM, which signals a need to renegotiate speed settings in the driver. This has been resolved by the latest sym/ncr driver pair which is currently undergoing final QA at Symbios and then will be released via Gerard to the mainstream linux kernel. Hence, it will be resolved shortly. Since the driver maintainer is taking care of this (and since I checked our internal tree and I can't see where the debug flag is still being set), I'm closing this as wontfix and waiting for the driver update to come through. In the meantime, you can load your sym53c8xx module with the option sym53c8xx=debug:0 to disable the debug messages.
I was wrong. A patch to our tree to disable the message has already been sent through by Pam Delaney and integrated into our CVS tree, so I'm going to close this as resolved/RAWHIDE instead.
Was this reported against wolverine or seawolf? It looks like it was wolverine. If that's the case will this fix be released in an errata update? (I hope so). Thanks
