If you're in a hurry, just use ABS. If you don't know how, now is a good time to learn ;-)

Re: kernel 2.6.25

Having issues with 2.6.25...

My filesystem is ext4dev, defaults,extents,relatime,nodiratime,data=ordered <- mount it so.

In 2.6.24, it's all ok. In 2.6.25, kernel fails to mount the fs due to unsupported options being possibly 'dangerous'.

It then panics as it cannot find root fs.

Watch out if you have ext4 then!

see this article:
http://lwn.net/Articles/266274/

Ted has proposed a new mount flag (called test_fs) which communicates to the kernel the user's understanding that they are about to mount a developmental filesystem and will not go filing lawsuits if things go wrong. In the absence of this mount option, an ext4 filesystem will refuse to mount.

OK but what does it mean and how to use it - is it mount option to be used 'mount -o test_fs' or something like that?
IMHO stupid idea - no documentation who to use it and forcing people to have something they don't need. I can't imagine that somebody use ext4dev in production env accidentally !

Re: kernel 2.6.25

thanks for the info.

to be honest, ext4dev seems pretty robust. and it indeed seems a stupid idea. there's a bloody 'dev' in the name isn't there? eh.

so for anyone with existing ext4dev filesystems, one needs to boot say a livecd (if your system is on ext4dev) and run:

[root]# debugfs -w /dev/sdXX
debugfs 1.40.5 (27-Jan-2008)
debugfs:  set_super_value s_flags 4
debugfs:  quit

according to: http://fedoraproject.org/wiki/FedoraExt4

I use e2fsprogs-interim, patches by me, available http://aur.archlinux.org/packages.php?ID=16506 <- here.

Re: kernel 2.6.25

my system is dead. did an upgrade as usual with pacman. Had no issues. I've booted from the new kernel-2.6.25 and no issues until last night.
I use a rt kernel for music production and when I tried to boot that kernel-2.6.24.rt, I got kernel panic. Tried to boot the 2.6.25 and that panic too.

now when I follow the debugfs thing, I get a message saying
/dev/sda3: Filesystem revision too high while opening filesystem.

How do I get out of this hell??? They was no warning when I did the upgrade.

Re: kernel 2.6.25

I just upgraded to 2.6.25 and everything runs great. It supports my 45nm xeon processor for coretemp module.

funkmuscle, I guess your issue has to do with the new ext4? Where is your /dev/sda3 mounted to?

Re: kernel 2.6.25

too late. lost everything. reinstalling Arch as we speak. 2.6.25 did run for a few days fine then the crash happened without any upgrading or package installed after installing 2.6.25.

I'm a musician and lost 100s of hours. Everything happens for a reason. the tunes will be better the 2nd time around. hehehehe!!!

thanx for the help everyone.
