Hi, Trying out 2.6.27-rc2-git4 on a VIA Ester + CX700 based system I experience the following panic using a config obtained with make oldconfig from working 2.6.26 config. Looking at the traces and when it happens it looks like it could be libATA or SCSI related... Note: the kernel is patched with viafb patches sent yesterday ([y]) and squashfs () lspci: 00:00.0 Host bridge [0600]: VIA Technologies, Inc.
