 Posted: Thu Jul 07, 2011 6:29 am Post subject: [SOLVED] Bizarre 2.6.36+ kernel freeze |
 |
|
Edit: Apparently, something possessed me to set CONFIG_INTEL_IDLE=y for a desktop system. Yeah... Live and learn.
This has been bugging me for months now. Currently, I am running gentoo-sources-2.6.34-r12 mostly because I am unable to upgrade my system to anything newer.
For example:
1. I take my 2.6.34-r12 .config and I copy it to a 2.6.36-r8 source tree.
2. I run make oldconfig and I try to configure the new kernel to the best of my abilities. Haven't had a problem with a Gentoo kernel in 8 years -- until now. I must be missing something trivial...
3. make && make modules_install, reboot and... the damn thing hangs. The last line I get is something like NET: Registered protocol family 17. Is there a way to make kernel output more verbose?

The kernel output can be made more verbose by addingto the command line in grub.
Try if setting | Code: | CONFIG_DEVTMPFS=y
CONFIG_DEVTMPFS_MOUNT=y |
in your .config helps. |

Did not help, unfortunately. This has got to be some configuration problem, since SysResqueCd-based kernels boot and run just fine. |

This sounds totally stupid now, but do you actual copy the new kernel to your boot partition by either run "make install" or copy the new bzImage to /boot?
Maybe you boot the old kernel all the time?
If the kernel config on the system rescue cd works and is a similiar kernel version, you could just use the /proc/config.gz for your new kernel. like
| Code: | | zcat /proc/config.gz > /usr/src/linux/.config |

Each time I recompile the kernel I copy the resulting bzImage to /boot, so that can't be the cause.

I know, but I'd rather avoid doing that. Besides having a clean .config I actually want to know what causes this! Last night I took a 2.6.34 .config and used it to run make oldconfig in a 2.6.36 tree. Comparing the resulting .config to the initial one, I just can't see what could possibly cause a freeze like this! The diff mostly contains a bunch of hardware config options for stuff I don't have, so it just boggles the mind. |
