Description of problem: According to the kernel changelogs, intel_idle gets loaded by default in kernel-2.6.35.6-39.fc14. This helped me find out what probably causes a problem with my Lenovo Ideapad S12 netbook. It seems intel_idle is causing the netbook to sleep 'too deep', which means even the clock won't run and if I have a download going on, it'll stop etc. The CPU is an Intel(R) Atom(TM) CPU N270. I've been able to work around this problem by adding 'nolapic' to the kernel line at grub.conf. I could report this upstream as well, if needed. Version-Release number of selected component (if applicable): kernel-PAE-2.6.35.6-39.fc14.i686 is affected kernel-PAE-2.6.35.6-36.fc14.i686 is not affected
Not fixed in kernel-2.6.36-1, it's actually even worse.
Please report this upstream.
This has already been reported upstream after I made the bug report here, I've added my comments to the upstream bug: https://bugzilla.kernel.org/show_bug.cgi?id=20172
For my Lenovo Ideapad S10-3 'nolapic' does not work. In this case SATA controller did not detected correctly. So only 'intel_idle.max_cstate=0' setting allows F14 to boot.
Re: Lenovo Ideapad S10-3 upstream commit 4731fdcf6f7bdab3e369a3f844d4ea4d4017284d "intel_idle: PCI quirk to prevent Lenovo Ideapad s10-3 boot hang" shipped in 2.6.36 Same patch shipped as 00f8646ef207c509072889c922d180cd28c923b9 and 2.6.35.8 Apparently FC14 shipped with 2.6.35.6, which doesn't include that patch.
This should be fixed in one of the errata kernels on F14 per comment #5
Actually, it's unsure whether this is fixed or not. See https://bugzilla.kernel.org/show_bug.cgi?id=20172#c39 and the next comment after that.
