Hi,
about checking for faulty hardware, to recap... So far I have
replaced the server, moved from i386 to amd64, and now I have also
replaced the eSATA PCI card. With all of these changes I am still
getting the panics.
On Monday I will swap out the drive enclosure and the cable which
should cover off the things you mentioned. Once Ive tested that Ill
let you know if Im still seeing the issue,
thanks Andy.
PS the disk enclosure is this:

Which according to the specs is using a Sil5744, I assume this is
providing the port multiplier support. Just in case thats of any help,
ie any know issues...
