系统: 惠普 Omen 15-5003nl
操作系统：Elementary OS Freya 0.3.2（和 Windows 10）
固态硬盘：SanDisk A110 SD6PP4M-256GB-1006
SSD 固件：A200906
核心：3.19.0-58-通用
我最近升级了我的 SSD 固件，它修复了 Windows 分区上的一个严重的 ahcpi 冻结错误（http://h30434.www3.hp.com/t5/Notebook-Boot-and-Lockup/HP-Omen-system-hangs/td-p/4990788)。有时系统也会在使用 Linux 操作系统时冻结几秒钟，所以我希望用这个新固件解决所有问题。
相反，现在我的 dmesg 充满了：

我检查了系统 SSD，没有发现任何错误。这是我的 smartctl 日志：

我尝试了几个内核（4.0.5、4.0.9、4.1.0、4.4、4.5），但都没有成功。我应该在其他地方报告这个错误吗？在哪里？你有什么建议吗？
更新 1：仅当插入交流电源插头时才会显示 Dmesg 错误。
答案1
显然，新的 SSD 固件与 TLP 配合得不太好（TLP 主页） 包裹。
打开 /etc/default/tlp 并注释
#SATA_LINKPWR_ON_AC=max_performance
#SATA_LINKPWR_ON_BAT=min_power
来解决问题。
