I have simmilar kind of problem that I would like to share with you  .

GE card was in the 3 slot for me in E250 , I had to move it to 1 st slot
then problems went away .
I had to re-arrange the differential SCSI cards in order to move the GE card
is first slot .
Sun told me that this is because ther are some issues if this card is in 3rd
slot (Bottom ) .

Could you please check if it is same case with E450 as well ?

Hi,

We've got E450s using ge driver as well - no issues on these machines.

No, we're not using Trunking anymore. We tried to use it, hit problems then
removed it to see if that was causing the hard hangs. We still saw the
issues when running 2 cards and pushing the machine hard.....
