>Number: 3565 >Category: kern >Synopsis: using MPU401 driver pagefaults kernel >Confidential: yes >Severity: serious >Priority: low >Responsible: freebsd-bugs >State: open >Class: sw-bug >Submitter-Id: current-users >Arrival-Date: Fri May 9 07:50:04 PDT 1997 >Last-Modified: >Originator: Ada T Lim >Organization: >Release: FreeBSD 2.2-STABLE i386 >Environment: Using TB Tropez in MPU401 mode. This is a hardware emulation of the MPU401 - requires an OS be downloaded onto the card at bootup. >Description: Basically, using the Tropez in MPU401 mode pagefaults the kernel. One tries to play a midi note, and *boom*, down goes the system. >How-To-Repeat: Boot DOS. Run setupsnd.exe and load oswf.mot into the soundcard. Either c-a-del or run fbsdboot.exe. playmidi -e <somefile.mid> *bang* there it goes. This method (boot dos, configure the card, then boot to OS of choice) has worked with OS/2 and Linux in the past. >Fix: Workaround: use the really crappy OPL3 on the card. >Audit-Trail: >Unformatted:
