Bonjour à tous.
Après recompilation du kernel 2.6.21, j’ai un joli message d’erreur:
"vfs: cannot open root device “sda5” or unknown-block(0,0)"
suivis du magique kernel panic.
Alors, j’ai évidemment suivi le tuto proposé sur ce forum et je termine la compilation via la commande:
make-kpkg --append-to-version “-zorro” --us --uc --initrd --added-modules=nvidia-kernel kernel_image modules_image kernel_headers
(donc le initrd est bien mi)
Mes infos: dmesg (sous la version 2.6.18 foncitonnelle)
ata1: SATA max UDMA/133 cmd 0xE800 ctl 0xE402 bmdma 0xD800 irq 177

ata2.00: configured for UDMA/133
Vendor: ATA Model: ST3250823AS Rev: 3.06
Type: Direct-Access ANSI SCSI revision: 05Je suppose donc que je dois cocher tout ce qui a rapport avec sata VIA dans les options kernel.
mais rien n’y fait 
voila mon dernier .config foireu: (j’ai tout coché en module 
)

Le debian boot alors la dessus:
itle Debian GNU/Linux, kernel 2.6.21-zorro
root (hd0,4) (j'ai remi le 0 à la main)
kernel /boot/vmlinuz-2.6.21-zorro root=/dev/sda5 ro
initrd /boot/initrd.img-2.6.21-zorro
savedefault
Voila… je comprend plus
P.S: A chaque nouvelle compilation, il me met dans grub des root (hd1,4) au lieu de (hd0,4) à chaque fois… et me remet un boot d’une ancienne compile (qui avai foiré aussi) du 2.6.21.
Bref, ca me saoul 
merci d’avance 
Edit: j’ai également rechargé le .config du kernel 2.6.18 actuel en faisant ensuite un make oldconfig et validant “n” pour chaque nouvelle fonction => fonctionne pas non plus…
