Exclamation help! ACPI trouble with Suse Linux 10.0 and KDE 3.5

Hi, I have recently reinstalled SuSE linux 10.0 on my laptop and after I got the system up and running I ran a system update using YaST to update to kde 3.5.1 and then updated the kernel.

Since then, when i attempt to shutdown or reboot my computer and press esc to see whats happening I get the following message at the end where the system umounts the HD partitions

[run command: shutdown now, and at the very end i get:]

unmounting file systems
dev/hda1 umounted
devpts umounted
tmpfs umounted
sysfs umounted
umount: /: device is busy
Oops: unmount falied :-( --trying to remount readonly...
mount: /is busy
mount: can't find /dev in etc/fstab or /etc/mtab
mount: /is busy
extra sync...
... hope now its ok to reboot
stopping udevd
umount: /proc: device is busy
mount: proc already mounted
umount: /proc: device is busy
umount: /proc: device is busy
The System will be halted immediately
Following this the system hangs...

Im not sure how long this had been going on before the update, as I wasn't looking for it

I thought this may be due to a bootloader geometry mismatch, but sfdisk -d /dev/hda | sfdisk --no-reread -H255 /dev/hda didn't solve it, and the partition table looks exactly the same as what the bootloader (GRUB) thinks it should be, so its not a mismatch.

So more likely its an ACPI issue, this is supported by the fact that KPowersave won't work on startup - i.e i get the warning message "KPowerSave isn't running, starting it will improve performance" and the warning screen "plug in the power cable immediately" because it thinks there is less than a minute left on my battery charge. When i get the status of KPowersave it tells me its 'unused', when i try to restart it it either crashes my desktop or starts and then crashes straight after

Im pretty sure ACPI is supported on my Laptop, as its pretty new and ACPI worked when i installed kde 3.4 before with the old kernel

Im really worried about it because nothing saves before the reboot becuase i have to pull the plug on it to turn it off, so I lose all saved files, and I guess it can't do the HD much good either...

by the way, Every time i reboot, i get the message trans replayed i think this means it hasn't shutdown properly, which i think must be due to ACPI settings

I know i probably need to do something to the Kernel but i haven't got a clue about compiling the kernel or adding bits to it

If anyone could help I would really appreciate it


Im using a dual boot SuSE Linux (10GB) Windows XP (60GB) system, kde 3.5.1, kernel version (unknown), 1 GM RAM, ATI mobility radeon 9600 graphics card 128MB RAM.

Could you(if possible) show us the whole shutdown process? I think the problem may be that you dont send all the processes the TERM signal so they dont shut down. Since your system is acting very weird try disabling acpi at the GRUB boot screen.

Thanks for responding, sorry for the delay...

i tried disabling ACPI at the grub bootloader using acpi=off and noapic, and it made no real difference, so i guess it can't be ACPI after all!

I had a look through the shut down procedure and it does appear to give the KIll and TERM signals and lay out the appropriate bits. I tried booting from the rescue cd, but when i went to shut it down (init 0), it unmnounted all the filesytem parts and then powered off perfectly. So i think then that it must be something to do with my fstab file, ive posted it below:

/dev/hda6   /           reiserfs    acl,user_xattr    1 1
/dev/hda1   /windows/C  ntfs        ro,users,gid=users,umask=0002,nls=utf8 0 
/dev/hda5   /swap       swap        defaults          0 0
proc        /proc       proc        defaults          0 0
sysfs       /sys        sysfs       noauto            0 0
usbfs       /proc/bus.usb  usbfs    noauto            0 0
tmpfs       /dev/shm    tmpfs       defaults          0 0
devpts      /media/dvdrecorder   subfs
noauto,fs-cdfss,ro,procuid,nosuid,nodev,exec,iocharset=utf8  0 0
Im starting to get really worried as my system is getting slower and slower as i keep having to pull the plug on it to shut it down...

do you have any idea what my fstab should look like?
