There are actually 3 relevant patches in the latest upstream kernel
(22.214.171.124) for this issue:
2010-11-19 Tejun Heo sata_via: apply magic FIFO fix to vt6420 too
2010-06-02 Tejun Heo sata_via: magic vt6421 fix for transmission
2010-06-07 Tejun Heo sata_via: explain the magic fix
ELRepo has updated drivers for sata_via available that fix this issue
for both EL5 and EL6:
As this isn't really a CentOS Development issue, can I ask that we take
any discussion of the above to the elrepo mailing lists and/or bug tracker:
