I wouldn't be surprised if there's a > z3fold bug somewhere. >=20 Hmm - yesterday i recompiled 6.9.12 with zsmalloc and =E2=80=A6. after = 16h of continuous tests I can=E2=80=99t reproduce issue. With zsmalloc 6.9.12 looks to me like stable. With this - what will be your advice to move forward? Is there any possibility/way to avoid bisecting? (due limited time from = my side)
