mám taký menší problém, nainštaloval som si na server Debian 4.0 r0 s pôvodným jadrom 2.6.18-4-486. Mám tam 2x 160gb HDD v RAID1 (softwarový RAID).
Keďže tento kernel je už opmerne starý, tak som išiel nahodiť 2.6.21.5. Načítal som config terajšieho kernelu, doplnil niektoré moduly a podobne, všetko prebehlo v poriadku.
Avšak, keď chcem nabootovať Linux cez nové jadro dostanem túto chybu:
.......
Begin: Mounting root file system... ...
Begin: Running /scripts/local-top ...
Begin: Loading MD modules ...
md: raid1 presonality registered for level 1
Success: loaded module raid1.
Done.
Begin: Assembling all MD arrays ...
mdadm: No devices listet in conf file were found.
Filature: failed to assemble all arrays.
Done.
Done.
Begin: Waiting for root file system... ...
Vedel yb mi niekto pomôcť? Vďaka
no, pokial nemas oznacene partiie ako raid auto detect, tak si budes musiet adaptovat initrd. a pozri si aj ovladace k tvojej doske (radicu diskov) ci si ich zahrnul do jadra alebo initrd.
Keď som dával nový kernel a disky neboli v RAID-e, tak všetko fungovalo v pohode

Patch som nedával.

apt-get install libncurses5-dev make gcc bin86 libc6-dev kernel-package bzip2 ale to asi vies :))
potom
cd /usr/src/linux-2.6.x.x/
make oldconfig :)
a tak klasika
make menuconfig # popridavat ca potrebujes
make bzImage
make modules
make modules_install
Vela stastia
