I have also this problem with Kubuntu 6.06 LTS. I installed new 686
kernel, because I use VM Ware a lot and last times I made shut down
properly. Perhaps new multiprocessor kernel helped. I use currently
version 2.6.15-28-686 of my kernel. Motherboard is Gigabyte 8IPE1000
with Intel 865PE chipset and power supply is QTec 500W ATX Bigfan LN
(Item 13981-02). CPU is Intel Pentium IV by 2,4 GHz.
Sometimes I mentioned, that logging off before shutting down might also
Certainly are those things very disturbing and I already think, that is
really Ubuntu the distro I want... If it is so broken and there are more
bugs than allowed to work properly...
One tip for crashed system - press keyboard keys as followed with few
seconds between them and monitoring HDD activities:
1) ALT+SysRq+R - enable keyboard raw mode
2) ALT+SysRq+S - synchronize filesystems (this step prevents data loss)
3) ALT+SysRq+E - terminate all programs
4) ALT+SysRq+I - kill all programs (in case terminate didn't work)
5) ALT+SysRq+S - sync again (might also not necessary)
6) ALT+SysRq+U - unmount all filesystems
7) ALT+SysRq+B - reboot computer
8) ALT+SysRq+O - shut down computer
If keyboard raw mode does not work then you may need to add to
/etc/sysctl.conf the following row:
kernel.sysrq = 1
... and do restart to service:
sudo /etc/init.d/procps restart
Or you can also recompile your kernel and allowing magic SysRq key.
Actually in Kubuntu is keyboard raw mode allowed by default even you
don't see this row in /etc/sysctl.conf
But I should unfortunaltey say, that if Kubuntu is crashed, I mean it
will not do shut down properly, then this keyboard raw mode trick does
not work :(
But sometimes this trick will work and is quite useful. I found also
