New submission from VOROSKOI Andras <[EMAIL PROTECTED]>: DragonFly 1.13-DEVELOPMENT #1: Mon May 19 23:26:51 CEST 2008 crashes on a simple mount_cd9660 /dev/cd0 /mnt/cdrom.

Also i was lazy to add the memory addresses too for the functions, let me know if you miss them or anything else. One more thing: using /dev/acd0 works fine. ---------- messages: 4657 nosy: voroskoi priority: bug status: unread title: mount_cd9660 crashes the kernel _____________________________________________________ DragonFly issue tracker <[EMAIL PROTECTED]> <https://bugs.dragonflybsd.org/issue1016> _____________________________________________________
