Five officers shot and wounded in Minnesota, authorities say_我的网站

调解面对面

一 | PRINCETON, Minn. -- Five law enforcement officers were shot and wounded Thursday in an incident near the east-central Minnesota city of Princeton, authorities said.The suspect was not in custody and the incident was ongoing late Thursday morning.Three of the officers were taken to North Memorial Hospital in the Minneapolis suburb of Robbinsdale while two were taken to a hospital in St. Cloud, said Robbinsdale Police Capt. John Elder, who was assisting the hospital, and added that none of the wounds appeared to be life-threatening.Elder said he did not immediately know which departments the wounded officers were from, but that they came from multiple agencies.The Benton County Sheriff’s Office provided few details in its initial statement. The department said it was being assisted by several other public safety agencies on a “critical incident” unfolding in Glendorado Township, which is a few miles west of Princeton. It said there was no danger to the general public, although the public was being asked to avoid the area.Video from KMSP-TV showed numerous law enforcement vehicles at the scene and officers in tactical gear.The area is about 50 miles (80 kilometers) northwest of Minneapolis.。 8 月 26 日消息，科技媒体 Linuxiac 昨日（8 月 25 日）发布博文，报道称 Linux 创始人林纳斯 · 托瓦兹（Linus Torvalds）借助 AI，通过 24 个调试补丁、18 次内核启动，成功排查 Intel Xe 图形驱动中的内存破坏漏洞。托瓦兹描述本次排查过程为“地狱般的调试过程”，在其 Intel Battlemage G21（配备 16 GiB VRAM）上 GDM（GNOME 显示管理器）反复重启合成器，屏幕最终保持黑屏。附上相关截图如下：该问题出现在 Xe DRM 驱动的 Flat CCS 内存处理环节，根源来自 get_flat_ccs_offset () 函数的地址计算。该函数先计算保留 CCS 存储区的起始位置，再将地址向上对齐到 128 KiB 边界。但随后，低于这个计算地址的全部空间都被 VRAM 分配器当作可用内存。这样一来，合成器首次提交 GPU 任务便失败，GDM 随即重启合成器，系统陷入黑屏。托瓦兹表示，最终修复只涉及把错误的 round_up () 改为 round_down ()。不过，定位过程远比修复代码复杂：他累计添加 24 个补丁，用于逐步增加调试信息，并启动内核 18 次，才锁定内存破坏的具体原因。

二 | 托瓦兹表示在本次调试过程中，AI 承担添加调试代码和分析输出结果等大量重复工作。在调用处理过程中，AI 多次得出该问题无法解决的结论，不过在托瓦兹的多次协调指导下，不断推进让 AI 生成新的调试工具并分析结果，直至定位底层内存破坏。调查结束后，托瓦兹还让 AI 撰写了详细的提交说明。
