[linux-dvb] Driver crash (ARM Crash)

[Tim Schröder <tim.schroeder@epost.de>]

Hi there,

in my box (K6-2 300 on Apollo VP3) i always had a few problems with the
driver and my Hauppage card. Now i've been able to track it down a bit
and send some traces. 
I am using the current version of dvb-kernel and a 2.5.54 kernel.
Everything is installed as described in the README. And i am using the
driver with vdr.
when i am using my harddrive with DMA (udma, mdma) i see ARM crashes
with kernel OOPS. If the drive is using PIO everything runs stable. the
rest of the systems runs stable now for years with udma !
With PIO i get a blocky picture when i hear the driver write data onto
the disk.With DMA i get a perfect picture till the hole machine goes
oops.
If i am using timeshifting the driver oopses after a few seconds, if i
am just recording it runs a few minutes.
On 2.4.20 with the cvs-driver i had the same problems except that i
didnt saw a kernel oops and after rmmod/insmod everything ran o.k.
again.
I attached the "cat /proc/kmsg" traces i did remote. i didnt attached
the kernel oops yet (i will send it if someone is interested) because
the oops (unable to handle kernel paging request at virtual adress
xxxx)occurs endlessly on the screen and i'll have note it down by hand
and type it in again.

thanks
