My impression was most x86 BIOS's did NOT turn on SERR/PERR when I added that code to parisc-linux port (2000 or 2001 so) . HPUX was turning on SERR/PERR and so I was comfortable the HW was stable and it not crash under normal use unless something was really broken. There is certainly nothing architectural specific about SERR/PERR. I felt (at the time) this is more of a case of "if it's not reported to the user, we won't get blamed for it not working well." hth, grant - To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
