My FreeBSD/amd64 system has two processors, each with 2 out of 4 memory slots filled. The total RAM is 4Gb. In the BIOS there are options to enable "Software memory hole" and "Hardware memory hole". The only way to have the entire 4Gb of physical RAM enabled is to have "Software memory hole" only. Enabling the hardware hole leads to the detection of only 3.6Gb. From /var/run/dmesg.boot: usable memory = 3783233536 (3607 MB) avail memory = 3597369344 (3430 MB) Unfortunately, when "Software memory hole" is enabled -- regardless of whether the hardware one is enabled or not -- trying to transfer a file via firewire: fwcontrol -M mpg -R /store/videos/tape1.mpg leads to a panic instantly: Unread portion of the kernel message buffer: panic: vm_fault: fault on nofault entry, addr: ffffffffb0796000 cpuid = 0 Uptime: 2m10s Physical memory: 4087 MB Dumping 295 MB:fwohci0: Isochronous receive err 8402(long) fwohci0: Isochronous receive err 8402(long) fwohci0: Isochronous receive err 8402(long) fwohci0: Isochronous receive err 8402(long) fwohci0: Isochronous receive err 8402(long) fwohci0: Isochronous receive err 8402(long) fwohci0: Isochronous receive err 8402(long) fwohci0: Isochronous receive err 8402(long) 280fwohci0: Isochronous receive err 8402(long) fwohci0: Isochronous receive err 8402(long) 264fwohci0: Isochronous receive err 8402(long) 248fwohci0: Isochronous receive err 8402(long) 232fwohci0: Isochronous receive err 8402(long) fwohci0: Isochronous receive err 8402(long) 216fwohci0: Isochronous receive err 8402(long) fwohci0: Isochronous receive err 8402(long) fwohci0: Isochronous receive err 8402(long) 200 184 168 152 136 120 104 88 72 56 40 24 8 #0 doadump () at pcpu.h:194 194 __asm __volatile("movq %%gs:0,%0" : "=r" (td)); (kgdb) #0 doadump () at pcpu.h:194 #1 0x0000000000000004 in ??
