Actually, the patch posted above appears to be included in 3.13.0-44.73, which is currently in proposed (also see: #1402853). I suppose that warrants a 'Fix Released' status, though I'll leave that to the Ubuntu kernel team. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1296660 Title: Kernel oops: fb: conflicting fb hw usage astdrmfb vs VESA VGA (unable to handle kernel NULL pointer dereference / con_set_unimap+0x32 Status in linux package in Ubuntu: Confirmed Bug description: Booting hangs on a Ubuntu Trusty Tahr (development branch) [3.13.0-18-generic #38-Ubuntu SMP Mon Mar 17 21:40:06 UTC 2014 x86_64] based system.

Still in 3.13.0-43-generic. Furthermore, I have a strong suspicion this was fixed upstream in v3.18, even though Wolfgang reported v3.14 worked fine for him. https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9e326f78713a4421fe11afc2ddeac07698fac131 Can anyone test and confirm this solves the issue? I'm affected, though testing is tricky without console access. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1296660 Title: Kernel oops: fb: conflicting fb hw usage astdrmfb vs VESA VGA (unable to handle kernel NULL pointer dereference / con_set_unimap+0x32 Status in linux package in Ubuntu: Confirmed Bug description: Booting hangs on a Ubuntu Trusty Tahr (development branch) [3.13.0-18-generic #38-Ubuntu SMP Mon Mar 17 21:40:06 UTC 2014 x86_64] based system.

I had the same problem with Ubuntu 12.04 and kernel 3.13.0-37-generic
This solution working:
http://askubuntu.com/questions/169912/fb-conflicting-fb-hw-usage-inteldrmfb-vs-efi-vga-removing-generic-driver
but is incomplette. That helped me to make permanent fix:

ther run update-grub, reboot and the error message is gone. SInce the
