 |
|
Hi,
I'm currently using Gentoo on a Dell Inspiron 9400 notebook which has a Centrino dualcore CPU (Genuine Intel(R) CPU T2400 @ 1.83GHz). Kernel 2.6.15-gentoo-r1 crashes with the centrino-speedstep kernel module. This happened after I did the following:
| Code: |
modprobe speedstep-centrino
modprobe cpufreq-conservative
cpufreq-set -g conservative
|
Kernel says:
| Code: |

Anyone knows if the cpufreq-driver is compatible at all with this new cpu? Or, if that is the case, what might have gone wrong? Thanks for your input. |

| SMP and speedstep is flakey, so not really compatible/working properly is the answer to your question. |

I don't have any kernel panic with the packages I've used on my laptop. Have you tried using the same packages as the ones I mention in my HOWTO (including the masked kernel sources)? You might want to continue posting in the latter.

i think this issue is related to crappy ACPI on some of our laptops my Acer CoreDuo needs some updates from -mm sources to run stable plus -mm has a multicore scheduler that you would benefit from

Does it mean fixing the errors in the DSDT would be a possible solution?

Doesn't work with 2.6.15-gentoo-r5 either here. |
