Certainly worth a try, but probably won't help the second panic. In the
second panic, there were no SCSI failures -- this is not unlike my
experiences on non-AV quadras and 2.6 kernels where a SCSI failure would
occasionally occur during device and partition probing. And if it didn't
fail at that point, there would be no SCSI trouble at all. This first
panic looks similar.
The second panic looks ADB related (the Q700 doesn't have CUDA ADB). I
would try booting with no ADB devices plugged in (or make sure the ADB
drivers don't load, if modular). Note that there is no serial console
support, which means that you won't be able to log in to shutdown except
remotely. So if you are going to try this, first enable journalling and
make sure ethernet and remote login works, or just boot with all
filesystems readonly.
