Dotaz: problemy po zkompilovani noveho jadra

[Wolf]

ahoj, zkompiloval a nainstaloval jsem si jadro 2.4.26-gentoo a ted pri 100% zatizeni procesoru skoro nejde hybat mysi a zda se mi ze i KDE je o neco pomalejsi.

predtim jsem mel 2.4.22-gentoo a tam to bylo bez problemu, nastaveni jadra jsem moc nemenil jen pridaval emulaci ide-scsi.

nevite nekdo cim by to mohlo byt, pripadne na co se zamerit?

Nezrusil jste si v jadre podporu pro vas chipset ? Vetsinou pak nejedou disky v DMA modu coz se takhle projevuje. kouknete na hdparm /dev/hda ... (jinak tohle je takove vystreleni od boku)

[Wolf]

dma je zapnute

vlastne jsem jeste pridaval podporu ACPI, ale to je vypnute pres acpi=off v grubu...

[Pinky]

kompiloval jsi se zapnutym preemtible kernel(procesor * eatures). Doporucuji skusti 2.6 kernel, je v pohodě.(mam ho na gentoo)

[Wolf]

jo mam CONFIG_PREEMPT=y

prechazet na 2.6 se mi zrovna moc nechce

[Pinky]

Mozna by stalo za pokus pouzit na ty dva configuraky kernel diff, ale verzemi jsou dost daleko od sebe takze to bude asi na pytel

[Wolf]

kernel diff je neco specialni, nebo myslis normalni diff? dik

[vdusek]

A proc mas 100% zatizeni procesoru? To prece neni normalni. Co treba primarne vyresit tento problem ;)

[Wolf]

ja ale nechci resit 100% zatizeni procesoru, ale tu mys. a 100% zatizeni samozrejme nemam porad, jen jsem ted aktualizoval system a bylo to trochu casteji...

[master_up]

Ten předchozí kernel ti chodil v pohodě, tak vzít konfiguraci starýho kernelu, konfiguraci novýho (daj se uložit do souboru třeba přez make menucofig jesli vis ocobezi) no a prez diff jen zjistis v cem se ta konfigurace lisi. Ale je to asi spatnej napad, protoze se budou asi lisit hodne a pak se v tom vyznej ďas. tos dělal přez genkernel ??.

[Wolf]

pres make menuconfig. porovnaval jsem zmeny (v menu) a vyslo z toho tohle:
ve starem jadre SCSI primo v jadre v novem jako modul
v novem jadre navic Cryptographic API, podpora ide-scsi, Per partition statistics in /proc/partitions z diffu vylezlo tohle (jestli se v tom nekdo vyzna tak je fakt dobrej ). doufam ze me admini nesejmou za zahlcovani DB

No nic nevidim, skus zjistit co znamenaji tzhle dva (moc jim ale nafandim) CONFIG_BLK_DEV_IDE_MODES=y CONFIG_BLK_STATS=y asi budeš muset skusit ještě jinek kernel.

[Wolf]

nefunguje to spravne ani kdyz to zkompiluju se stejnym nastavenim jako to stary jadro, vzdavam to
