Description Yuri 2012-01-21 20:03:41 UTC
I find this message in kdm.log on FreeBSD-9.0 when I try to start kde4. Investigating a bit, I got this information: This message is printed by package libpciaccess-0.12.1, file src/freebsd_pci.c in it. Rebuilding this package doesn't help. The error 'failed to set mtrr: No space left on device' results from system call ioctl(fd, MEMRANGE_SET, &mro) @ freebsd_pci.c:146. fd there is the fd for /dev/mem Parameters of this ioctl call are (mro.r.mr_base=40000000 mro.r.mr_len=10000000 mro.r.mr_flags=2 mro.r.mr_owner="pciacces" mro.mo_arg=0 mro.mmo_arg=0) This system only has 1GB memory, mr_base=40000000 is already at 1GB, so mr_len=10000000 makes it out of range? That's why it maybe failed. This issue is also mentioned in FreeBSD PR#ports/164350 libpciaccess-0.12.1

ajax, can you take a look at this.

I'm not a FreeBSD person, but I'd expect -ENOSPC to mean that you're already out of MTRRs.
Comment 3 Matthieu Herrb 2012-08-12 17:24:06 UTC
Seeing that too on OpenBSD with a thinkpad X220. I confirm that it's caused by the MTRR table beeing full already (filled by BIOS) when starting X.
