[vdr] arm crash by disk start

[Rainer Zocholl <UseNet-Posting-Nospam-74308-@zocki.toppoint.de>]

Hello

Today i thought it would be a good day to powerdown 
the unused second disk.

That leads very reproducible to non recoverable arm "cashes"...

To "crash" the arm I did something like:

#tail-f /var/log/yslog /var/loh/messages
#
#umount /dev/hdc4
##sent to deep sleep
#hdparm -Y  /dev/hdc4
#
#sleep 5
#
##wake the disk
#hdparm -t  /dev/hdc4
#mount /dev/hdc4 /mnt
#df /dev/hdc4
#

vdr tries to restart without any success...


The disk is runinng in DMA. the 900kB/s sems to include the spinuptime.
A second test shows the usual 30MB/s.
