In the boot I see that he recognize my chip and turn on DMA on hda and hdb (My HD) , but when it try to start DMA on my hdc (first DVD Reader) It locks up with "hdc: DMA disabled" message, then it said about the device that is BUSY , then it said "ide1: resetting!" and return to the message above ("hdc:DMA...:") in an infinite loop.I don't know what to do.I've tried to install ac2 patch for linux-2.4.20 tree, and it don't lock up to hdc: DMA disabled (this appears again , but don't freeze here) but when I try to enable ide-scsi module it freeze with messages about SCSI problems, then it tries to resetting all the SCSI emulated devices and this create an infinite loop of these messages! What is the problem? Thanks a lot Bye Marcello
