How to upgrade the kernel? -- Linux general technology-Linux technology and application information. For details, refer to the following section. To upgrade to kernel 2.6.26.2, should the etx3 and etx2 file systems be compiled into the kernel or compiled into a module?
Why do I see two online statements? Is there any expert who can provide specific guidance?
Next I will list the supported options of kernel etx3 File System 2.6.26. Hope Gao can give a guide on * or M selection:
File system --- "[] Ext3 journalling file system support
[] Ext3 extended attributes
[] Ext3 POSIX Access Control Lists
[] Ext3 Security Labels
JBB (ext3) debugging support (why does this item not exist in my Kernel configuration options? Because I have seen a saying that this item also needs to be selected .)
Previously, I selected M as the first item and then * as the last three items *. However, the following problems occur after the system is restarted:
No filesystem cocould mount root, tried: iso9660
Kernel panic: VFS: Unable to mount root fs on unknown-block (3,9)
