--- Comment #1 from Christian Zigotzky (chzigotzky at xenosoft.de) ---
I have the same problem with my analog PCI TV card Typhoon TView RDS + FM
Stereo (BT878 chip) in my AmigaOne X5000. It only works with reducing the mem
size to 3500MB (mem=3500M).
I figured out that the issue is somewhere in the PowerPC updates 4.21-1 [1].
Maybe the code change in the file "arch/powerpc/kernel/dma-swiotlb.c" [2] or
maybe the change in the file "arch/powerpc/kernel/dma.c" [3].
