我的笔记本电脑晚上处于睡眠模式,早上无法唤醒,而是过了一会儿就将我发送到欢迎屏幕,关闭所有正在运行的程序(我知道的)。
显然,我去查看了syslog
,那里确实出现了一些警告/错误/失败。
以下是其中几点:
Jun 26 09:39:51 lati kernel: [152504.094113] ACPI Error: Index value 0x0000000000000083 overflows field width 0x7 (20140424/exfldio-343)
Jun 26 09:39:51 lati kernel: [152504.094116] ACPI Error: Method parse/execution failed [\NEVT] (Node ffff88040e047258), AE_AML_REGISTER_LIMIT (20140424/psparse-536)
Jun 26 09:39:51 lati kernel: [152504.094119] ACPI Error: Method parse/execution failed [\_SB_.PCI0.LPCB.ECDV._Q66] (Node ffff88040e044b90), AE_AML_REGISTER_LIMIT (20140424/psparse-536)
(这些可能与Dell e7440,睡眠有时会失败,内核日志显示 ACPI 错误)
然后是这些:
Jun 26 09:39:51 lati kernel: [152504.467188] ata2.00: failed to get NCQ Send/Recv Log Emask 0x1
Jun 26 09:39:51 lati kernel: [152504.467571] ata2.00: failed to get NCQ Send/Recv Log Emask 0x1
(可能与启动时出现失败消息。我可以延迟启动吗?或者如何解决?)
然后是这些:
Jun 26 09:39:51 lati bluetoothd[718]: Unknown command complete for opcode 19
Jun 26 09:39:51 lati bluetoothd[718]: hci0: Set Secure Simple Pairing (0x000b) failed: Busy (0x0a)
然后再次出现 ACPI 错误:
Jun 26 09:39:54 lati kernel: [152508.018847] ACPI Error: Index value 0x0000000000000083 overflows field width 0x7 (20140424/exfldio-343)
Jun 26 09:39:54 lati kernel: [152508.018858] ACPI Error: Method parse/execution failed [\NEVT] (Node ffff88040e047258), AE_AML_REGISTER_LIMIT (20140424/psparse-536)
Jun 26 09:39:54 lati kernel: [152508.018869] ACPI Error: Method parse/execution failed [\_SB_.PCI0.LPCB.ECDV._Q66] (Node ffff88040e044b90), AE_AML_REGISTER_LIMIT (20140424/psparse-536)
然后出现一些compiz
错误:
Jun 26 09:40:02 lati kernel: [152515.489573] traps: compiz[2396] general protection ip:7ff4391c4c34 sp:7ffeff248248 error:0 in libframe.so.6.0.0[7ff4391bf000+1c000]
以下是其中的一些:
Jun 26 09:40:02 lati NetworkManager[811]: <info> Unmanaged Device found; state CONNECTED forced. (see http://bugs.launchpad.net/bugs/191889)
(有关的:“非托管设备”是什么意思?)
然后网络管理器出现错误:
Jun 26 09:40:20 lati NetworkManager[811]: <error> [1466923220.217192] [nm-system.c:1266] nm_system_replace_default_ip6_route(): (wlan2): failed to set IPv6 default route: -7
(有关的:NetworkManager 无法设置 IPv6 默认路由)
然后有东西杀死了 compiz:
Jun 26 09:40:26 lati gnome-session[2211]: WARNING: Application 'compiz.desktop' killed by signal 11
Jun 26 09:40:26 lati gnome-session[2211]: WARNING: App 'compiz.desktop' respawning too quickly
Jun 26 09:40:26 lati gnome-session[2211]: CRITICAL: We failed, but the fail whale is dead. Sorry....
(可能相关:从挂起或启动唤醒后 GUI 重新启动 ('应用程序'compiz.desktop'已终止..),“严重:我们失败了,但是失败的鲸鱼已经死了。抱歉……”)
然后
Jun 26 09:40:26 lati bluetoothd[718]: hci0: Remove UUID (0x0011) failed: Busy (0x0a)
然后
Jun 26 09:40:31 lati NetworkManager[811]: <warn> error requesting auth for org.freedesktop.NetworkManager.wifi.share.open: (3) GDBus.Error:org.freedesktop.DBus.Error.NameHasNoOwner: GDBus.Error:org.freedesktop.DBus.Error.NameHasNoOwner: Could not get UID of name ':1.193218': no such name
(有关的:NetworkManager 上的 NameHasNoOwner 警告)
然后
Jun 26 09:40:33 lati signond[1015]: ../../../../src/signond/signondaemon.cpp 388 init Failed to SUID root. Secure storage will not be available.
(可能相关:https://bugs.launchpad.net/ubuntu/+source/signon/+bug/1182007)
最后:
Jun 26 09:41:02 lati gnome-session[694]: GLib-CRITICAL: g_environ_setenv: assertion 'value != NULL' failed
(可能相关:Dell e7440,睡眠有时会失败,内核日志显示 ACPI 错误)
错误相当多,但结果是重新启动,这是所有这一切的真正糟糕后果。
我保留了一份副本syslog
,以防您认为其中任何内容可能有助于分析这个问题。
