Friends, [NOTE: Please CC me on replies. Thanks.] I'm having trouble with cdrecord when recording audio CD's. During the write process, a buffer underrun will occur and cdrecord will stop and report the error. This typically happens around the 5th track. When I try again, it happens almost immediately. Further, my hard drive continuously cranks away and they system becomes hardly useable. A 'halt -p' takes about 30 minutes to completely shut down the computer... and that's the only way I've found to stop it. Upon review, after the first failure the system becomes sluggish. After the second failure it becomes unusable. This doesn't appear to happen when recording data disks. This happened with several brand new CD-R disks (which are now coasters). This happens at 1x, 4x, and 8x speed. Happens in -DAO and -TAO. This happens even in -dummy mode. Happens when su'ed to root... happens when logged in as root. I first noticed it when running K3B... but I've since isolated it as a cdrecord problem. Questions: Is this happening to anyone else? STFW yields nothing. Is it me, or is it a bug? If a bug in cdrecord -- how do I report it when the Fedora distribution has "altered" it to add "DVD" and so the program spits out the disclaimer "do not notify the author of problems with this version?" ...following is way too much information. :-) Thanks in advance!
