Basic Info of my system: ABIT BP6 w/ two 500MHz Celeron chips, a 52X ATAPI Creative CD-ROM drive as /dev/hda and a 18GB IBM UDMA-66 HDDs as /dev/hde.
Working kernels: Debian Potato 2.2.15-ide and 2.2.17-Pre6 installed on /dev/hde. Problem: I was trying to recompile the 2.2.17-Pre6 kernel in order to enable SMP and optimise the performance of my Linux system. However, got an error message of 'Kernel Panic: VFS can't mount '/' on 21:09'. It seems to me that the newly build kernel does not have UDMA-66 support. How can I fix it? If this is not the reason, could anyone please tell me what could be wrong? N.B. The first Linux was installed from 2.2.15-ide floppies with UDMA-66 support. And then it was upgraded to 2.2.17-Pre6 from the Debian TC3 Unofficial CD-ROMs, still detected my HD which was connected to the ATA-66 IDE channel. Many thanks for your help!
