Hang up the System!
It's so easy to crash the system:
1. ) Put an unnecessary harddisk with hdparm into sleeping mode (in this case its my windoof hdd)
2.) do a simple "fdisk -l"
3.) Your system hangs, nothing does work then anymore.
No network services etc....
only the kernel responds to the "magic - keys".
Its a RedHat system with kernel 2.4.20.
How can i solve this problem?
