Maybe this will shed some light on it. ;) I happen to have a suitable docking station for my Precision M4500.
The real problem is this: ============================================ [ 0.088777] BUG: unable to handle kernel paging request at ffffffffcccafed0 [ 0.095752] IP: [<ffffffffcccafed0>] 0xffffffffcccafed0 [ 0.100992] PGD 1a2c067 PUD 1a2d067 PMD 0 [ 0.105148] Oops: 0010 [#1] SMP [ 0.108421] last sysfs file: [ 0.111378] CPU 0 [ 0.113222] Modules linked in: [ 0.116492] [ 0.117984] Pid: 0, comm: swapper Not tainted 2.6.35-19-generic #28-Ubuntu 041WH1/Precision M4500 [ 0.126833] RIP: 0010:[<ffffffffcccafed0>] [<ffffffffcccafed0>] 0xffffffffcccafed0 [ 0.134488] RSP: 0000:ffffffff81a01e08 EFLAGS: 00010002 [ 0.139784] RAX: 00000000cf5de878 RBX: 0000000000004650 RCX: 00000000746e7665 [ 0.146913] RDX: 0000000000000000 RSI: 0000000000004650 RDI: 00000000cf65d280 [ 0.154046] RBP: ffffffff81a01f38 R08: 0000000000000001 R09: 0000000000048000 [ 0.161174] R10: 0000000000000000 R11: 0000000000048000 R12: 0000000000000030 [ 0.168301] R13: 0000000000048000 R14: 0000000000000001 R15: 0000000000046000 [ 0.175415] FS: 0000000000000000(0000) GS:ffff880001e00000(0000) knlGS:0000000000000000 [ 0.183491] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 0.189227] CR2: ffffffffcccafed0 CR3: 0000000001a2a000 CR4: 00000000000006b0 [ 0.196349] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 0.203472] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 [ 0.210584] Process swapper (pid: 0, threadinfo ffffffff81a00000, task ffffffff81a32020) [ 0.218653] Stack: [ 0.220658] 00000000cf65d34b 00000000746e7665 0000000000000000 ffff88012fc046e0 [ 0.227924] <0> ffffffff81a01ec0 0000000000000000 8000000000000000 0000000000000200 [ 0.235672] <0> 00000000cf5de8a0 00000000cf5dee18 00000000cf5de878 0000000000000000 [ 0.243608] Call Trace: [ 0.246050] [<ffffffff81031fd6>] ? efi_call4+0x46/0x80 [ 0.251271] [<ffffffff81afea91>] ? efi_enter_virtual_mode+0x15b/0x284 [ 0.257786] [<ffffffff81aedc26>] start_kernel+0x310/0x390 [ 0.263260] [<ffffffff81aed341>] x86_64_start_reservations+0x12c/0x130 [ 0.269857] [<ffffffff81aed43f>] x86_64_start_kernel+0xfa/0x109 [ 0.275854] Code: Bad RIP value.

On my machine takes a second or 15 between the BIOS screen disappearing and (for now) Windows 7 boot screen appearing when booting normally. In between there seems to be some hard disk activity, as if the BIOS scans all partitions for boot loaders. ** Attachment added: "kern.log" https://bugs.launchpad.net/ubuntu/+source/casper/+bug/635439/+attachment/1571969/+files/kern.log -- No UEFI boot on Dell Precision M4500 https://bugs.launchpad.net/bugs/635439 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
