Remember that you had to disable machine checks when firing up the CPU's on the 2100: /* lower the ipl and take any pending machine check */ mc_expected = 1; alpha_mb(); alpha_mb(); alpha_pal_wrmces(7); (void)alpha_pal_swpipl(ALPHA_PSL_IPL_HIGH); mc_expected = 0; Maybe this is relevant to that? -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
