General--LinearSolve and Precision: Impossible to solve 8x8 matrix

Greetings,

wp = 25; (* WorkingPrecision Value *)
pr = 20; (* SetPrecision Value *)
( **** Complexe functions ****)

Dimensions[L]={8,8}.
Dimensions[Y]={8}.
L and Y are function of x.
K = Normal[Series[LinearSolve[L, Y], {x, 0, 1}]]];

I can not have result for this linear system within a reasonnable time and with a good precision. Any suggestions will be very welcome.
Cheers.
