Acer AT115 F1 systems will panic when booting the x86 (32bit) Red Hat Enterprise Linux 5.5 kernel

Issue

Acer AT115 F1 systems will panic when booting the x86 Red Hat Enterprise Linux (RHEL) 5.5 kernel. x86_64 installs on these platforms boot properly.

Environment

Red Hat Enterprise Linux 5.5 (x86)

Resolution

A fix is available in a RHEL 5.5+ erratum.  The erratum announcement may be found at the following URL link: http://rhn.redhat.com/errata/RHSA-2010-0398.html   If want to run x86 kernels on AMD Magny-Cours platforms will need to  install RHEL 5.4 x86 and then upgrade to RHEL5.5+ erratum in that order. Please contact your Red Hat Support representative for further  details on the 5.5+ errata release.The workaround described above will be the best solution to the issue until the release of RHEL 5.6.  This is because Red Hat does not respin update release ISOs to include fixes that have been released in subsequent errata.  The first install media that will contain the fix in the listed errata will be the RHEL 5.6 discs and ISOs.
