 Posted: Sun Sep 30, 2012 8:45 am Post subject: [solved] no message from "init 2(or 3)"l |
 |
|
If I install a kernel in a straight manner | Code: | | make -j5 && sudo su -c "mount /boot/; make install && make modules_install && cp arch/i386/boot/bzImage /boot/vmlinuz" |
Then the last message I'll seen at the console during boot is | Code: | | NX-protecting the kernel data: 2396k |
Then the boot continues w/o any output until the login prompt appears.
A genkernel-generated kernel acts as expected.
Any hints ?
FWIW if I use the kernel line "init 2", log in as root and then type "init 3" - I'll see all subsequent messages.
Here's my config (I'm using as much as possible as modules) : http://bpaste.net/show/48441/

toralf ... I suspect this is due to having inteldrmfb built as a module (CONFIG_DRM_I915=m), so no framebuffer to display console messages.
best ... khay |

Well, same happens if I built all into the kernel (simply deactivated modules). |

toralf ...
OK, well, here is a diff of our respective configs (re graphics display). I'm not sure with KMS its advisable to have FB_MODE_HELPERS, or VGACON_SOFT_SCROLLBACK.

A genkernel-generated kernel acts as expected. |
After that message is printed, does the screen change modes? Do you have appropriate device nodes in your static /dev? |

ah - this question points me to the interesting direction - yes, the mode is changed. And I do have only /dev/null and /dev/zero in /dev, all other nodes I let create by udevd.
And I cleaned up the /dev few weeks days ago. The old device nodes I moved to /var/tmp: | Code: | tfoerste@n22 /var/tmp $ ls -l | grep -e ^c -e ^l

| Put console back into your static /dev or enable DEVTMPFS_MOUNT so that the kernel mounts devtmpfs for you. Otherwise, your /dev/console will not exist until udev starts and mounts devtmpfs. By the time that happens, various programs have already picked a non-functional stdout/stderr. |

DEVTMPFS_MOUNT was missing - thx  |
