1. vmalloc - vfree vmalloc在虚拟内存空间给出一块连续的内存区,实质上,这片连续的虚拟内存在物理内存中并不一定连续,所以vmalloc申请的虚拟内存和物理内存之间也就没有简单的换算关系,正因如此,vmalloc()通常用于分配远大于__get_free_pages()的内存空间,它的实现需要建立新的页表,此外还会调用使用GFP_KERN的kma...
The network adapter freezes the entire system, when you try to enable power management under Linux. Is this maybe related to the EEE issue that's causing the disconnects? https://community.intel.com/t5/Ethernet-Products/Power-management-bug-in-I226-V-Linux-kernel-driver/m-p/1612996 https...
For any of our customers experiencing this problem, a mitigation option to explore is to disable the “Energy Efficient Ethernet (EEE)” mode in the Advanced Windows/ Linux driver setting. We believe this should help. We are continuing to assess the situation a...
After much googling, it appears that there is a bug in the Linux kernel being used in Proxmox 8 with that particular ethernet card related to auto-negotiation because of some power savings features on switches. So until the kernel/ethernet driver is fixed in Proxmox(...
