|
|
Hello,
Since kernel 3.x.x have kernel panic....
My system: /boot on sda1 with ext4 file system
motherboard intel dq35jo with sata intel ich9r/d0/dh in ahci mode
Gentoo system on SSD Intel on sda
and 3 sata hard drive in raid5 soft (mdadm) for /home
(mdadm.conf --> ARRAY /dev/md/gentoo:0 metadata=1.2 name=gentoo:0 UUID=4742dbea:5d7bcf11:8d9fee53:8ca860b7)
and 1 sata hard drive for video
and 1 sata optical drive
and usb card reader
my /etc/fstab
Code: |
/dev/sda1 /boot ext4 noauto,noatime,discard 1 2
/dev/sda3 / ext4 noatime,discard 0 1
/dev/sda2 none swap sw 0 0
/dev/sdb /mnt/cdrom auto noauto 0 0
/dev/md0 /home ext4 noatime 0 2
/dev/sde1 /video ext4 noatime 0 2
# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
# POSIX shared memory (shm_open, shm_unlink).
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will
# use almost no memory if not populated with files)
shm /dev/shm tmpfs nodev,nosuid,noexec 0 0
|
/boot/grub/device.map
Code: |
(hd0) /dev/sda
(hd1) /dev/sdb #possible mistake ??? sdb is optical drive in fstab
(hd2) /dev/sdc
(hd3) /dev/sdd
(hd4) /dev/sde
|
my grub.conf:
Code: |
default 0
timeout 5
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
title=kernel-2.6.39-gentoo-r3d By Chris_Y2k
root (hd0,0)
kernel /boot/kernel-2.6.39-gentoo-r3d
title=kernel-3.2.1-gentoo By Chris_Y2k
root (hd0,0)
kernel /boot/kernel-3.2.1-gentoo-r2 root=/dev/sda1
|
2.6.39 kernel works fine but with kernel-3.2.1-gentoo-r2
have a kernel panic:
Code: |
...
VFS: Mounted root (ext4 filesystem) readonly on device 8:1.
devtmps: error mounting -2.
Free unused kernel memory : 568K
Kernel panic - not syncing : No init found . Try passing init = option to kernel
...
|
my kernel 3.2.1-r2 config...

In your grub.conf:
Code: |
kernel /boot/kernel-3.2.1-gentoo-r2 root=/dev/sda1
|
Should this be:
Code: |
kernel /boot/kernel-3.2.1-gentoo-r2 root=/dev/sda3
|
?
(According to /etc/fstab, /dev/sda1 is your boot partition
with /dev/sda3 mounted on /. So /sbin/init would be on
/dev/sda3.)
PS:
Do you really want swap on an SSD device? _________________ TIA |

Merci beaucoup !
A big Thank You !!! WCG
I can wrote this message with my new functionnal kernel ....
for my old motherboard(Intel DQ35JO chipset serie 3) the ssd speed up my computer have only 4Go of ram.
If my system must swap i prefer the swap reside on rapid ssd (my older intel ssd Serie 320 - near 130Mo/s for writing and 267Mo/s for reading with 0.2ms acces time)
SSD is a fantastic upgrade, today i can't use a computer without SSD |
