Hi All,

I have serious trouble using the mantis driver from
http://jusst.de/hg/mantis.

After loading the driver and using it in conjunction with VDR, the PC freeze
after a while (10min to 6h).
"Freeze" in this case means, that the PC does not react on any action (using
the remote, keyboard, ping or anything else) but the TV-Livesignal and sound
are still on the TV!

Just before this "freeze" happend, I recognized many "mantis start/stop feed
& dma" in dmesg.

Jul 9 08:55:21 vdr kernel: mantis_alloc_buffers (0): DMA=0x2ed90000

Some Information about the system:
Linux myserver 2.6.24.7 #1 SMP Tue Jul 8 16:40:13 CEST 2008
One AMD x86_64 1000MHz processor, 2010.54 total bogomips, 511M RAM
System library 2.7.0

lspci -vs 01:07.0
01:07.0 Multimedia controller: Twinhan Technology Co. Ltd Mantis DTV PCI
Bridge Controller [Ver 1.0] (rev 01)
    Subsystem: TERRATEC Electronic GmbH Unknown device 1178
    Flags: bus master, medium devsel, latency 32, IRQ 22

What's wrong?
Do I have to use a different kernel version?
Are there any preconditions to take in account?

Thanks for your help
