of course I remember you - you're THE Reiser4 expert ! Of course after me (just joking )
glad to see you again, buddy
ok, think I'll give (at least) BFQ a try and (if it works) BFS also |
Yeah, I've been busy for a while. Mostly work/maintenance on my server and just life. It's been a log while since I've done any testing with reiser4. I haven't had a problem in a long time. I should do some more runs on performance since r4 got some major cod updates with 2.6.37 _________________ Atlas (HDTV PVR, HTTP & Media server)

v15 fails to boot. i get an error that says something similar to kernel not working, falling back to the backup kernel, not working either. v14 worked just fine. |

ok never mind, i built the initrd image in a wrong place. i built it in the kernel build directory instead of /boot. fixed my problem after i copied it over to /boot |

V15 is crashing on brtfs. It allows you to mount it, but any ls/cd operation will crash the kernel. No idea about previous versions, as this was the first one I tried.

you have backups, right ?
just to be sure - I read about the following: [PATCH] fix (latent?) memory corruption in btrfs_encode_fh()
if that already is in 2.6.37 included, nothing to worry about
*) the trigger or cause can either be the io-less dirty throttling patchset - so the same also should appear in the current zen-kernel
*) or it's caused by zcache - then please test a vanilla 2.6.37 with the zcache-patch only
*) or if you're NOT using nfs - try disabling that whether that makes a change
thanks for testing ! _________________ https://github.com/kernelOfTruth/ZFS-for-SystemRescueCD/tree/ZFS-for-SysRescCD-4.9.0

Of course I've got backup. I wouldn't test any new kernel if I couldn't afford data loss
I will zcache-patch only later this week. _________________ 95% of all computer errors occur between chair and keyboard (TM)

ok,
good luck & have fun
I'm currently not using btrfs since it's too "unstable" for me - in the sense that randomly data-corruption occurs after hardlocks, resume from suspend, etc.
so it's not worth it for me right now
therefore I also can't say anything about if btrfs works on this kernel patch(set) since I haven't tested it ... _________________ https://github.com/kernelOfTruth/ZFS-for-SystemRescueCD/tree/ZFS-for-SysRescCD-4.9.0

no, i just used your latest patch with the zcache memory leak fix. no linuxdna. compiler flags were "-O3 -mssse3 -ip -fp-model fast=2 -unroll-aggressive -vec-guard-write -march=native" i will try some more compiler flags. maybe even -fast. didn't get a single error during compiling. and it boots up as well. and i think i just gained about a performance boost of 5 fps in compiz. before it was 44, now its 48 - 49 ish with compiz cube.

i dont have a lot of modules. but the few modules that i did have were compiled successfully and work properly so far. dont know about virtualbox though. i will try installing it and see if it works. |

yeah, you need to compile the modules with icc as well. my gcc compiled virtualbox modules don't work in the new kernel. but, if you install virtualbox from the binary uploaded on their website, you don't need to compile the modules. they work with all compilers. |

I'm pretty new to this whole icc thing:
would there be any problems when compiling kernel-modules ?
I guess I would need to compile them with icc, too ? (e.g. virtualbox-modules) |
source /opt/intel/compilerpro-12.0.2.137/bin/compilervars.sh ia32 (or intel64)
make AR=xiar LD=xild && make AR=xiar LD=xild modules_install
and that's pretty all.
works fine here.
to set env. for portage installation of packages with icc.
nano /etc/env.d/05icc
PATH=/opt/intel/compilerpro-12.0.2.137/bin/ia32
ROOTPATH=/opt/intel/compilerpro-12.0.2.137/bin/ia32
LDPATH=/opt/intel/compilerpro-12.0.2.137/compiler/lib/ia32
MANPATH=/opt/intel/compilerpro-12.0.2.137/man _________________ this is a strange strange world. |

also, here is another thing that you can do. add icc to your use flags. then portage will compile everything with icc if it is known to not break the system. ah man, cant wait till i get my new desktop, that way i can screw around and install gentoo on it and not worry about my mom yelling at me. xD. |

Really ? the portage is smart enough to know which package will not break with icc ?
and I can't find any package with icc use flag... |
