Hello! I'm getting this backtrace every time I boot: resource map sanity check conflict: 0xf0000000 0xf1ffffff 0xf1000000 0xf112bfff BOOTFB ------------[ cut here ]------------ WARNING: CPU: 6 PID: 1 at /home/proskin/src/linux/arch/x86/mm/ioremap.c:171 __ioremap_caller+0x372/0x380() Info: mapping multiple BARs.

Hello! I have spent some time on the issue. I'm not sure it's a nouveau bug. I have a fix that changes arch/x86/kernel/sysfb_simplefb.c only. GRUB actually uses graphic mode on my card. That mode is supported by simplefb. However, the resource conflict happens regardless of whether simplefb is enabled. It's sysfb_simplefb that causes it, a completely different driver. If GRUB keeps the graphic mode, I have this entry in...

You can set CONFIG_X86_SYSFB=n and everything works fine. It's the default and is what pre...

Hi, I’m struggling with virsh not detecting my hugepage mount. I have the following kernel command line: BOOT_IMAGE=/vmlinuz-4.8.13-gentoo root=/dev/mapper/gensd-gentoo ro quiet splash intel_iommu=on video=efifb:off,vesafb:off,simplefb:off splash=verbose,theme:livedvd-aurora kvm.ignore_msrs=1 transparent_hugepage=never hugepages=3072 softlevel=qemuvm My startup script outputs the following: hugetlbfs /var/lib/hugetlbfs hugetlbfs rw,relatime,pagesize=2097152,uid=77,gid=77,mode=0770 0 0 [2016.12.13 22:22:50 virsh 2808] ERROR Faile...

...ther, sorry. I simply tried another approach to pacify the resource checker. However, there is some difference. nvidiafb cannot access the resources if IORESOURCE_BUSY is used. It's not that it matters for me. nvidiafb fails on my hardware anyway and I don't need it when I already have simplefb and nouveau. But I think we should have a closer look why it fails and what other drivers may fail. -- Regards, Pavel Roskin
