With the IDE driver, there was a #define but that's not the case with the libata one. Thank Alan Cox for that. :-) However, it shouldn't be hard to do, just comment out the following lines: if (clock_slot < 2 && ppi[0] == &info_hpt370) ppi[0] = &info_hpt370_33; if (clock_slot < 2 && ppi[0] == &info_hpt370a) ppi[0] = &info_hpt370a_33; [the rest skipped] -- You are receiving this mail because: You are watching the assignee of the bug.
