DVD's and DVD-R's seem to be recognized fine when inserted; however CDs (pressed, cdr, cdrw, audio) are not. I always end up with a message to effect of "No media found" when trying to use those. I googled for quite a bit, but wasn't able to narrow the problem down. I don't know if it is the promise driver or something in the ide-cd module. A fair bit of my log looks like the following after trying various mounting operations. cdrom: open failed. cdrom_pc_intr, write: dev hdf: flags = REQ_STARTED REQ_PC REQ_QUIET sector 0, nr/cnr 0/0 bio 00000000, biotail 00000000, buffer 00000000, data 00000000, len 0 cdb: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 hdf: cdrom_pc_intr: The drive appears confused (ireason = 0xd0) cdrom: This disc doesn't have any tracks I recognize! I am running vanilla-2.6.14-rc2 no enhancements. The drive itself worked fine in another computer. Any ideas on where to go hunting? I can provide lots of info if needed, just give me a idea of what.
