I just don't see how in a computer like that will be installed a kernel 2.6 . So why code of math-emu isn't dropped ?=20 Btw I try install a kernel 2.4 in my DX2 and works but very very slow . I think in this type of computer should be install a kernel 2.2 .=20 Thanks, --=20 S=E9rgio M.B. --=-BXRSNryns0KGoH3z8FhX Content-Type: application/x-pkcs7-signature; name=smime.p7s Content-Disposition: attachment; filename=smime.p7s Content-Transfer-Encoding: base64 MIAGCSqGSIb3DQEHAqCAMIACAQExCzAJBgUrDgMCGgUAMIAGCSqGSIb3DQEHAQAAoIIGSTCCAwIw ggJroAMCAQICAw/vkjANBgkqhkiG9w0BAQQFADBiMQswCQYDVQQGEwJaQTElMCMGA1UEChMcVGhh d3RlIENvbnN1bHRpbmcgKFB0eSkgTHRkLjEsMCoGA1UEAxMjVGhhd3RlIFBlcnNvbmFsIEZyZWVt YWlsIElzc3VpbmcgQ0EwHhcNMDUxMTI4MjIyODU2WhcNMDYxMTI4MjIyODU2WjBLMR8wHQYDVQQD ExZUaGF3dGUgRnJlZW1haWwgTWVtYmVyMSgwJgYJKoZIhvcNAQkBFhlzZXJnaW9Ac2VyZ2lvbWIu bm8taXAub3JnMIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEApCNuKD3pz8GRKd1q+36r m0z7z+TBsbTrVa45UQsEeh9OQGZIASJMH5erC0u6KbKJ+km97RLOdsgSlKG6+5xuzsk+aqU7A0Gp kMjzIJT7UH/bbPnIFMQNnWJxluuYq1u+v8iIbfezQy1+SXyAyBv+OC7LnCOiOar/L9AD9zDy2fPX EqEDlbO3CJsoaR4Va8sgtoV0NmKnAt7DA0iZ2dmlsw6Qh+4euI+FgZ2WHPBQnfJ7PfSH5GIWl/Nx eUqnYpDaJafk/l94nX71UifdPXDMxJJlEOGqV9l4omhNlPmsZ/zrGXgLdBv9JuPjJ9mxhgwZsZbz VBc8emB0i3A7E6D6rwIDAQABo1kwVzAOBgNVHQ8BAf8EBAMCBJAwEQYJYIZIAYb4QgEBBAQDAgUg MCQGA1UdEQQdMBuBGXNlcmdpb0BzZXJnaW9tYi5uby1pcC5vcmcwDAYDVR0TAQH/BAIwADANBgkq hkiG9w0BAQQFAAOBgQBIVheRn3oHTU5rgIFHcBRxkIhOYPQHKk/oX4KakCrDCxp33XAqTG3aIG/v dsUT/OuFm5w0GlrUTrPaKYYxxfQ00+3d8y87aX22sUdj8oXJRYiPgQiE6lqu9no8axH6UXCCbKTi 8383JcxReoXyuP000eUggq3tWr6fE/QmONUARzCCAz8wggKooAMCAQICAQ0wDQYJKoZIhvcNAQEF BQAwgdExCzAJBgNVBAYTAlpBMRUwEwYDVQQIEwxXZXN0ZXJuIENhcGUxEjAQBgNVBAcTCUNhcGUg VG93bjEaMBgGA1UEChMRVGhhd3RlIENvbnN1bHRpbmcxKDAmBgNVBAsTH0NlcnRpZmljYXRpb24g U2VydmljZXMgRGl2aXNpb24xJDAiBgNVBAMTG1RoYXd0ZSBQZXJzb25hbCBGcmVlbWFpbCBDQTEr MCkGCSqGSIb3DQEJARYccGVyc29uYWwtZnJlZW1haWxAdGhhd3RlLmNvbTAeFw0wMzA3MTcwMDAw MDBaFw0xMzA3MTYyMzU5NTlaMGIxCzAJBgNVBAYTAlpBMSUwIwYDVQQKExxUaGF3dGUgQ29uc3Vs dGluZyAoUHR5KSBMdGQuMSwwKgYDVQQDEyNUaGF3dGUgUGVyc29uYWwgRnJlZW1haWwgSXNzdWlu ZyBDQTCBnzANBgkqhkiG9w0BAQEFAAOBjQAwgYkCgYEAxKY8VXNV+065yplaHmjAdQRwnd/p/6Me 7L3N9VvyGna9fww6YfK/Uc4B1OVQCjDXAmNaLIkVcI7dyfArhVqqP3FWy688Cwfn8R+RNiQqE88r 1fOCdz0Dviv+uxg+B79AgAJk16emu59l0cUqVIUPSAR/p7bRPGEEQB5kGXJgt/sCAwEAAaOBlDCB kTASBgNVHRMBAf8ECDAGAQH/AgEAMEMGA1UdHwQ8MDowOKA2oDSGMmh0dHA6Ly9jcmwudGhhd3Rl LmNvbS9UaGF3dGVQZXJzb25hbEZyZWVtYWlsQ0EuY3JsMAsGA1UdDwQEAwIBBjApBgNVHREEIjAg pB4wHDEaMBgGA1UEAxMRUHJpdmF0ZUxhYmVsMi0xMzgwDQYJKoZIhvcNAQEFBQADgYEASIzRUIPq Cy7MDaNmrGcPf6+svsIXoUOWlJ1/TCG4+DYfqi2fNi/A9BxQIJNwPP2t4WFiw9k6GX6EsZkbAMUa C4J0niVQlGLH2ydxVyWN3amcOY6MIE9lX5Xa9/eH1sYITq726jTlEBpbNU1341YheILcIRk13iSx 0x1G/11fZU8xggHvMIIB6wIBATBpMGIxCzAJBgNVBAYTAlpBMSUwIwYDVQQKExxUaGF3dGUgQ29u c3VsdGluZyAoUHR5KSBMdGQuMSwwKgYDVQQDEyNUaGF3dGUgUGVyc29uYWwgRnJlZW1haWwgSXNz dWluZyBDQQIDD++SMAkGBSsOAwIaBQCgXTAYBgkqhkiG9w0BCQMxCwYJKoZIhvcNAQcBMBwGCSqG SIb3DQEJBTEPFw0wNjA5MjAwMDQ4MzZaMCMGCSqGSIb3DQEJBDEWBBRjkFGEvt3EWytKc2pNVlm8 FoSdRDANBgkqhkiG9w0BAQEFAASCAQCKkYq6qAwlB8gakaHSb5+G14A+VVYX25907Xoer2J6mPCe buxE9z+2walEoxhXWRCMBqw3DPBIai6Smyr9e9TJD0L4symjyX2kbe1c3jxLhDE/Ru+ld+6c1fYn uEtT2Fa3vneHEqJLnRjCqpZJgvVeqHJxu2+5hVRIxH6sZOZwMuV12XHkXGGUX6Fc1mp3f9DAS3wK Oj9j8ZBKme2t6S+FIQgHELP5GdIyHkX6J9aQ2RDXTH3tk71d5KIM+MTXIoCfWZYJN/dUlCWiFkGD Z78WsJ4HoW0+f+yajdpCTLA4E/OT/bv6kyUZjzx8D4YnSjwVtRYYPIqqJgjqsplV5UvNAAAAAAAA --=-BXRSNryns0KGoH3z8FhX-- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
