With this patch applied (on 4.1.4 and 4.3-unstable), I've got original sy= mptom - only CPU0 active after ACPI S3. Didn't get reboot after few tries. "xl debug-key r" output attached. Anyway it looks like bug was introduced somehow between 4.1.2 and 4.1.3 -= on 4.1.2 none of above problems happened. --=20 Best Regards / Pozdrawiam, Marek Marczykowski Invisible Things Lab --------------080109000601000203000902 Content-Type: text/plain; charset=UTF-8; name="xl-debug-key-r--only-cpu0-active.txt" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="xl-debug-key-r--only-cpu0-active.txt" KFhFTikgc2NoZWRfc210X3Bvd2VyX3NhdmluZ3M6IGRpc2FibGVkCihYRU4pIE5PVz0weDAw MDAwMDU5MkMzRjYyOUQKKFhFTikgSWRsZSBjcHVwb29sOgooWEVOKSBTY2hlZHVsZXI6IFNN UCBDcmVkaXQgU2NoZWR1bGVyIChjcmVkaXQpCihYRU4pIGluZm86CihYRU4pIAluY3B1cyAg ICAgICAgICAgICAgPSA0CihYRU4pIAltYXN0ZXIgICAgICAgICAgICAgPSAwCihYRU4pIAlj cmVkaXQgICAgICAgICAgICAgPSAxMjAwCihYRU4pIAljcmVkaXQgYmFsYW5jZSAgICAgPSA0 NjYKKFhFTikgCXdlaWdodCAgICAgICAgICAgICA9IDUxMgooWEVOKSAJcnVucV9zb3J0ICAg ICAgICAgID0gMzcwOQooWEVOKSAJZGVmYXVsdC13ZWlnaHQgICAgID0gMjU2CihYRU4pIAl0 c2xpY2UgICAgICAgICAgICAgPSAzMG1zCihYRU4pIAljcmVkaXRzIHBlciBtc2VjICAgPSAx MAooWEVOKSAJdGlja3MgcGVyIHRzbGljZSAgID0gMwooWEVOKSAJbWlncmF0aW9uIGRlbGF5 ICAgID0gMHVzCihYRU4pIGlkbGVyczogMDAwMDAwMDAsMDAwMDAwMDAsMDAwMDAwMDAsMDAw MDAwMGUKKFhFTikgYWN0aXZlIHZjcHVzOgooWEVOKSAJICAxOiBbMC4xXSBwcmk9MCBmbGFn cz0wIGNwdT0wIGNyZWRpdD0yMDggW3c9NTEyXQooWEVOKSBDcHVwb29sIDA6CihYRU4pIFNj aGVkdWxlcjogU01QIENyZWRpdCBTY2hlZHVsZXIgKGNyZWRpdCkKKFhFTikgaW5mbzoKKFhF TikgCW5jcHVzICAgICAgICAgICAgICA9IDQKKFhFTikgCW1hc3RlciAgICAgICAgICAgICA9 IDAKKFhFTikgCWNyZWRpdCAgICAgICAgICAgICA9IDEyMDAKKFhFTikgCWNyZWRpdCBiYWxh bmNlICAgICA9IDQ2NgooWEVOKSAJd2VpZ2h0ICAgICAgICAgICAgID0gNTEyCihYRU4pIAly dW5xX3NvcnQgICAgICAgICAgPSAzNzA5CihYRU4pIAlkZWZhdWx0LXdlaWdodCAgICAgPSAy NTYKKFhFTikgCXRzbGljZSAgICAgICAgICAgICA9IDMwbXMKKFhFTikgCWNyZWRpdHMgcGVy IG1zZWMgICA9IDEwCihYRU4pIAl0aWNrcyBwZXIgdHNsaWNlICAgPSAzCihYRU4pIAltaWdy YXRpb24gZGVsYXkgICAgPSAwdXMKKFhFTikgaWRsZXJzOiAwMDAwMDAwMCwwMDAwMDAwMCww MDAwMDAwMCwwMDAwMDAwZQooWEVOKSBhY3RpdmUgdmNwdXM6CihYRU4pIAkgIDE6IFswLjFd IHByaT0wIGZsYWdzPTAgY3B1PTAgY3JlZGl0PTIwOCBbdz01MTJdCihYRU4pIENQVVswMF0g IHNvcnQ9MzcwOCwgc2libGluZz0wMDAwMDAwMCwwMDAwMDAwMCwwMDAwMDAwMCwwMDAwMDAw MywgY29yZT0wMDAwMDAwMCwwMDAwMDAwMCwwMDAwMDAwMCwwMDAwMDAwZgooWEVOKSAJcnVu OiBbMC4xXSBwcmk9MCBmbGFncz0wIGNwdT0wIGNyZWRpdD0yMDggW3c9NTEyXQooWEVOKSAJ ICAxOiBbMzI3NjcuMF0gcHJpPS02NCBmbGFncz0wIGNwdT0wCgo= --------------080109000601000203000902-- --------------enigFB036A0B5D2380FA3E5E1AA9 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://www.enigmail.net/ iQEcBAEBAgAGBQJQ05xzAAoJENuP0xzK19csmFAH/1BSgdlrMaN/uD6hmetMWrHw 3zozTE69KQTrXR3o4Z46lOuxEcb+OLn64wgnqgbR4KpqzaxtPUaadL2zXBzYM+sq oAqbncs9wjYB3DxCdfqMSUzWHIrILSKkVR76vD2jmt8tDBv4kmyKx+RFR84ebtcZ bKSFxRrz3XwiSTsVcxL0Tqt9UGCpnu0QGTsG/qwSQ4xZGgPk1CZnG18XAfCmWoK2 mJJ54gZn7Wunqut2Sm8pzRJg5VvGumLHTeqzPS6GZe7fgXfKtugxswfjV8o8niDs IKsUh/KVEHg4jQfvwT7nzovkrA0z5BZ1T2AlkmjXiiEs9EhgwBcCl1QJNsKuknc= =987B -----END PGP SIGNATURE----- --------------enigFB036A0B5D2380FA3E5E1AA9-- --===============1744327927895738521== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel --===============1744327927895738521==--
