I've just finished building an LFS 6.1.1 system. It boots ok until it prints
the following messages:

ieee1394: raw1394: /dev/raw1394 device initialized
ACPI: PCI interrupt 0000:00:03.3[D] -> GSI 23 (level, low) -> IRQ 23
ehci_hcd 0000:00:03.3: Silicon Integrated Systems [SiS] USB 2.0 Controller
ehci_hcd 0000:00:03.3: BIOS handoff failed (112, 1010001)
ehci_hcd 0000:00:03.3: continuing after BIOS bug...

ehci_hcd 0000:00:03.3: new USB bus registered, assigned bus number 1

After this it hangs. Any help would be greatly appreciated.

Hi,

Could be a BIOS bug (as stated in the output), but that would also have happened with the host linux you used to build LFS. So I doubt that that is the problem.

Do you actually have ehci? Shouldn't that be uhci.
If that is the case: Recompile your kernel without ehci (and, if not activated, with uhci).

Hope this helps.

i believe i have ehci:

0000:00:03.0 USB Controller: Silicon Integrated Systems [SiS] USB 1.0 Controller (rev 0f) (prog-if 10 [OHCI])
0000:00:03.1 USB Controller: Silicon Integrated Systems [SiS] USB 1.0 Controller (rev 0f) (prog-if 10 [OHCI])
0000:00:03.2 USB Controller: Silicon Integrated Systems [SiS] USB 1.0 Controller (rev 0f) (prog-if 10 [OHCI])
0000:00:03.3 USB Controller: Silicon Integrated Systems [SiS] USB 2.0 Controller (prog-if 20 [EHCI])

Hi,

Looks like it. But also OHCI. Are both activated?

You could decide, for the time being, to remove all USB support. Get your box up and running first with the basics. This kernel could also be used later on as a fall-back kernel (extra boot option in grub/lilo). This has the advantage that you can always boot, even if you mess-up your primary kernel and end up with a kernel panic/hang.

The problem you describe are most of the time kernel related, something you (wrongly) activated or did not activate. Finding out which can be a pain, but working systematically will eventually solve the problem.

Don't know if the following is 'old news', but you can use the lspci (-v) command to get some extra info. You could also take a look at the dmesg output that is created by the host system you used (live cd?) and use that as a base.

Not that much to go on, but I hope it helps anyway.

ill have a look at that when i get a chance. thanks for your help.
