hello
when I'm typing "reboot" my computer (linux slackware-current, 2.6.6) display messages on screen - this is ok !
but when (the last one is) Rebooting.....
I have two more messages: !

shutdown hdc
shutdown hda

I don't whant this !!

somebody help !?

shutdown -h now (total shutdown)
shutdown -r now (reboot) (not sure about the now)

I haven't try shutting down as a normal user; I use root to shutdown and reboot. Are you trying to shut down as normal user?

I'm typing command "reboot" as root
I don't set this yet (that normal user can)

I don't understend that harddisk going down - when I do reboot !!
this is something wrong !

This is normal..

when you reboot, all hardware resets.. thats why it's called reboot.
the 2.6.6 kernel has a new way of flushing the IDE devices at shutdown or reboot, that's why you didn't see this before whit earlier kernels

this isn't normal !!
this is shit !!

this is bad for harddisk !!

is any change to set this back ? (2.6.5)

I don't get your problem really

The only thing that happens is the cache of the disk is flushed, and then the drive suspends.
This does not damage your drive

It would be another story when the disk was actally powered down, but that isn't happening here. It only suspends, meaning it goes into a 'low-power mode'.

I have total shutdown ! TOTAL !!!!!

not suspends mode or somethings ! - total off !

and you tested this with a meter?

lol !!!!!!!!!!!!!!!


I hear that disc switches itself off totally !!!!!
After restart, in moment of detecting of discs - My disc starts just and fly to wait 5 seconds to he took speeds


sorry for English !

but I tell you - my disc(s) isn't in any "suspend mode", "sleep mode"
or somethings else !

Actually, that is normal.
its not sh!$, its supposed to happen that way.

Its not bad for harddisks at all..

Back in Winblowz world when you reboot your machine, the cache is flushed then all hardware activity is stopped and then restarted.

Even in the older kernels your drives stopped and then restarted, you just didnt get a message that they did that. Im not sure why you would want your drives to stay active on a reboot. are you getting errors on restart, which cause your excited concern?

I think you probably just notice it now because you are paying attention due to the messages. My system has always basically halted completely then restart. Don't worry, be happy :-)

Just reinstall your 2.6.5 kernel.

I have the same problem, but I'm using Fedora Core 2 (Kernel 2.6.5, older kernel in Core 1 didn't have this problem). From the menu bar, I select log out->restart computer, everything is normal, and the very last 2 lines before the restart are:

shutdown hda
shutdown hdb

Then the computer restarts. This actually spins down the drive, fully, not lower power or anything. The computer then promptly reboots, BUT in my case, while both drives are spinning up, the bios is searching for them, they don't spin up fast enough and the bios startup complains and says something like "primary master and slave not found, press f1 to continue..." etc etc and then waits indefinitely.

Now this is very bad since I have to be manually at the keyboard to reboot again (not to mention the damage caused to the drives every single restart). I sometimes restart my computer through VNC, not that isn't possible. I also have a dual boot setup between XP and Fedora, I don't boot into XP often, but now if I do, I'll be damaging my drives everytime.

Don't believe me? it's a known kernel bug (for IDE drives, SCSI drives are fine):

It's been fixed in the new kernels. Hopefully it will be released soon, I'm not really a kernel compiler, only been using Linux for a short while.
