Kloke >Release: FreeBSD 4.0-STABLE i386 >Organization: Inst f Arbeitsphysiologie Uni Dortmund >Environment: >Description: The Creatix PnP ISDN card uses addresses 0x120-0x13f and 0x180-0x1bf The driver /sys/i4b/layer1/i4b_ctx_s0P.c changes this by allocating new resources 0x20 lower. This conflicts with 2nd IDE adapter at 0x170. A kernel with enabled 2nd IDE and Creatix card crashes immedatiately after not getting the required resources. >How-To-Repeat: >Fix: I changed the length of the resource request from 0x20 to 0x10. Now the kernel works fine. The ungraceful handling of the error situation must be fixed, however, as the allocation method will probably fail in other situations also( e.g. a device in 0x100-0x1f region). >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
