[0]Hey, [0] [0]When the system boots and probes for devices, it reaches the matcd [0](matsushita cdrom ) and then goes into an infinite loop about the bus [0]not releasing. This has happenned on two different motherboards (intel [0]ZP and SiS P90). Whne I try to configure the boot to not probe for the [0]matcd, it just goes ahead and boots default. [0] [0]Thanks, [0]Lindsey [1]I had this problem also... The matcd0 probe interferes with a Sound [1]Blaster card... even if you havn't told FreeBSD that the card exists. [1] [1]Disabling the matcd is the correct solution to the problem... Actually the CORRECT solution is to get the newer matcd driver, which can be found in FreeBSD 2.1. It supports the sound card or host interface you have. The driver in 2.0.5 supports ONLY genuine Creative Labs cards. The man page for matcd actually listed that requirement in 2.0.5. The newer driver supports Creative Labs boards, plus IBM, Diamond, MediaVision, and half a dozen other vendors who make their CD-ROM interfaces different (not compatible) with the SoundBlaster. FYI, the matcd driver is looking for the CD-ROM interface which is where you got stuck and that hardware is completely INDEPENDENT of the audio sections of the card. So the audio-related drivers can be completely disabled and the CD-ROM section will still work. Get the new driver (/usr/src/sys/i386/isa/matcd/*) - it will run in 2.0.5 just fine, or upgrade to 2.1.0.
