I'm getting a "buss error" (signal SIGBUS) doing I/O with inb() and outb() to any port. This is running under FreeBSD 3.0-CURRENT, logged on as root. Before this, I do open("/dev/io",RW) and check any return error. gdb says that the signal was received in outbv()/inbv(). The following is an example: ¦#include ... outb(0x70, 0x0); x1=inb(0x71); outb(0x70, 0x02); /* <-------- a "buss error" here, core nicely dumped */ ... Does anybody have an idea what's going on? Any help/comments will be highly appreciated. Thank you all. -jcvp- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
