Software: Oracle 11gR2 oracleasmLib SUSE Linux Server 11.

Without installation of the oraclasm, the SUSE Linux 11 starts/reboots smoothly. Now, after installed oracleasmlib, I encountered the following weird situation:

When I issues oracleasm exit command,

A black screen appears and displays a long list of info. At its final pause, displays:

Saving dump using makedumpfile
Copying data: [1%] It keeps change to --> 2% --> ... 100%.

When it reaches the 100%, the system reboot.

Now, , I try to reboot/shutdown the OS. The same thing happens, that is,

A black screen appears and displays a long list of info. At its final pause, displays:

Saving dump using makedumpfile
Copying data: [1%] It keeps change to --> 2% --> ... 100%.

When it reaches the 100%, the system reboot.

Now, I remove the installed oracleasmLib, everything returns to normal, I can reboot and shutdown as usual.

This happens only after I installed the oracleasmLib. At this point, I can not shutdown the machine, because the above described cycle just keep going.

What could be wrong? How could I fix it? And, how could the oracleasm interferes with the OS?
