But this just gives > Dez 26 17:24:13: dtest kernel: UBSAN: array-index-out-of-bounds in sound/pci/ctxfi/ctamixer.c:344:48 > Dez 26 17:24:13: dtest kernel: index 10 is out of range for type 'unsigned char [9]' as the error. Making the struct even larger gives > Dez 26 17:39:35 dtest kernel: UBSAN: array-index-out-of-bounds in sound/pci/ctxfi/ctamixer.c:344:48 > Dez 26 17:39:35 dtest kernel: index 32 is out of range for type 'unsigned char [32]' Could you take another look?
