Hi all! I've got a Via Epia PD6000E, which has a VT8235 onboard - I've seen a kernel patch for viapm.c at http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/62438 It helped as the device is found - BUT after a few seconds, I get a panic: viapropm: SMBus I/O Base at 0x6000 ... Mounting root from ufs:/dev/ad0s1a kernel trap 12 with interrupts disabled Page fault virtual addr = 0x6c instruction ptr = 0x8:0xc04c4d11 current process 58 (sysctl) Well, the DDB says: db>trace turnstile_setowner turnstile_wait _mtx_load_step sysctl_kern_ttys sysctl_root userland_sysctl _sysctl syscall(2f,2f,2f,2f,2,bfbfe4ac) Xint0x80:syscakk --- syscall (202, , ) eip=0x280c2757 if started up without viapm.ko loaded, pciconf -l tells: isab0@pci0:17:0 class=0x060100 card=0xaa011106 chip=31771106 Has anyone seen similiar problems ? And additionally already solved ? I want to use this bus to access external devices via i2c; I think bitbanger via i2cbb / ppbus is not an option; as I need the printer port already George
