[gentoo-user] what does this mean:rcu_sched detected stalls on CPUs/tasks
My pc have a random boot problem.I can hardly make it clear when will occur.
The kern.log shows INFO: rcu_sched detected stalls on CPUs/tasks: { 0}
(detected by 1, t=10002 jiffies, g=18446744073709551325,
c=18446744073709551324, q=13).
When this happen on boot,the kernel seems hung and will take about one or
two minuts,then continue booting as normal.Does anyone know the reason?
Re: [gentoo-user] what does this mean:rcu_sched detected stalls on CPUs/tasks
Yes,I have search some webpages.But not sure if this question can be solved
and how to be solved.

Google search string: INFO: rcu_sched detected stalls on CPUs/tasks:
First hit: https://www.kernel.org/doc/Documentation/RCU/stallwarn.txt
That's the kernel doc that describes the relevant system.

Do you have /usr on a seperate partition?
If yes, do you use an initramfs to mount it at boot?

Please do not top-post.
I just noticed you are checking for display and xauthority in the
environment.
Udev processes events when they come in. I doubt you are logged in when
the mouse is detected during boot.
Try removing those checks from the rule.

[gentoo-user] gcc specs file change multilib_defaults no effect.
Hello,everyone. I found that the gcc specs file has such contents: // *multilib: . !m64 !m32 !mx32;64:../lib64 m64 !m32 !mx32;32:../lib32 !m64 m32 !mx32;x32:../libx32 !m64 !m32 mx32; *multilib_defaults: mx32 // I change it to: // *multilib: . !m64 !m32 !mx32;64:../lib64 m64 !m32 !mx32;32:../lib32 !m64 m32 !mx32;x32:../libx32 !m64 !m32 mx32; *multilib_defaults: m64 // expect to change gcc default target.But failed. If I don't add -m64 flag,I will still get a x32 abi target. So，is it possible to change the default target of gcc?

[gentoo-user] bios+gpt+grub2 boot windows
I format my hard disk to gpt.Then create a 1M partition at the header of hard disk ,add bios_grub flag.I can install and boot gentoo,debain and archlinux,but have no idea how to boot windows7 and 8.When I boot win7 or win8 from usb,it always complain the gpt partition and cannot install.What should I do?

Shatroff yks-...@yandex.ru: Well, actually it *is* possible using hybrid MBR+GPT partitioning. http://www.rodsbooks.com/gdisk/hybrid.html Also google for 'hybrid mbr'. I am using this setup for multibooting several OS incl. Win 7 without problems for a couple of years. I almost forgot about hybrid MBRs... also it's fragile indeed, so I probably won't recommend it even if I thought about it in the first place. In this case, you must either revert to an msdos partition table (can be done w/o data loss IIRC), or trick Windows into believing it's running on EFI, i.e. set up UEFI DUET. Google that and you'll find an excellent HOWTO on this. Happy hacking~ An interesting idea, yet, probably, a little more complicated than hybrid MBR for the sole purpose of multibooting. I've tried that on a VirtualBox VM last year, and I'd like to point out that describing the process as a little more complicated is serious underestimation. :D

[gentoo-user] Is it possible to use the x32 abi gcc version to build a amd64 system?
x32 abi is a new abi which is different from x86_64 and x86.Some softwares cannot compile on x32 system,but glibc,gcc,binutils,works well on x32 abi with faster speed than x86_64.So I would to make such a gcc version,its abi is x32,but its default target is x86_64,similar to cross compiler.Then I can build a x86_64 system with faster speed.The question is how to make such a gcc version?
