>Description:
I installed 2.0 to my hard disk. I noticed that my DESQA-SA NIC is now
recognized as a "delqa-plus in Turbo mode" instead of a plain "delqa".
When I run "ifconfig qt0", the kernel crashed:
# ifconfig qt0
qtpanic: Segv in kernel mode: pc 80143b86 addr 2e
I am using a VAX 4000 Model 700A, with the following modules:
slot one MS690-D
slot two MS690-D clone
slot three MS690-D clone
slot four MS690-D
slot five KA692
slot six DESQA-SA
slot seven DHV11-A
slot eight CMD CQD 223M
slot nine TQK50-AA
slot ten empty
slot eleven empty
slot twelve empty
