Subject: [2.6.27-rc2-git4] Kernel panic on VIA Ester+VIA CX700

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 (<m>)
