boot problem after upgrade from Redhat 6.2 -> Redhat 7.2
Posted on 2003-02-25
I have a customized system with AMDK6-2 400MHz CPU running RH 6.2 (no Xwindow). However, the system has an upgraded kernel of 2.4.18. Since sometimes the system complains that some applications have lower version than the kernel(i.e. mount), I decided to upgrade the system to RH7.2.
The system is running on a bare motherboard and has no CDROM and floppy drive. So I took the HD off and connected to a P4 box to do the upgrade. The HD can boot successfully on the P4 box after upgrading. However, after I connected the HD back to the original system, it could not boot correctly. The initialization stops after showing the following information:
EXT3-fs: mounted filesystem with ordered data mode.
VFS: Mounted root (ext3 filesystem) readonly.
Freeing unused kernel memory: 256k freed
Does anybody know why does this happened? How do I solve this problem?
