Hello all, I'm unable to use particular video cd under self-compiled kernel 2.6.18. Reading first 8 megabytes goes well, and then - bulk of errors and nothing. The same cd works perfectly under windows xp sp2 on the same machine - system can mount it, read its contents and play it. BUGGIE MONSTER WARNING: This optical drive is somehow.... special :D Have you ever erased dvd-r or dvd+r medium? Well, now I have done it too.... First, I put a dvd recorded half a year ago. It worked fine. Once. Second time, the system was just unable to read anything from the cd. I tried it on another machine - winxp said the dvd is empty, but was unable to record anything there of course. Then, after some study, I discovered each sector of the disc can be read one time, max. two times - after this its contents is lost. What is interesting hovewer, it does not actually happen all the time - sometimes everything works just perfect, sometimes dvd is destroyed. Especially when recording a dvd (what works always fine) I try to read it it gets 'erased' - nothing such was observed on windows, but I can't tell it does not happen ever - just haven't investigated. This cd is however bought, so I suspect it is not recorded - system fails tests on the original, and on its copy (which has been successfully made on another machine with nero). The symptomes are always the same. However, on windows it just works fine. The machine is AMD Athlon 64 3200+ 1GB RAM. The magic drive is LG GSA-H20L (it's IDE). I've upgraded the firmware from 1.00 to 1.01, because I thought it could help - it didn't. Attachments - .config and two dmesgs. The first is what happens when I try to use xine - first seconds (8mbytes) works fine, and then this (note - the kernel was tainted then by ati's fglrx driver - that's why i've done the second test). The second test is done without xwindows (kernel is not tained though) - i've tried dd if=/dev/hda of=/dev/null - that's how i now the first 8 megs work fine. It includes the startup messages too. You can see I have reloaded cdrom driver with debug=1 there, hoping it will expose some usefull info - it seems it didn't however. I will be gratefull for your responses - especially to the vcd case, because it is very repetitive (note - the problem is with this particular vcd - i have other that works fine). The dvd mysterious is I think too mysterious to investigate it without some..... ide packet dump? -- wixor
