I have this with usb1&2umass (txt_sysctl_with_umass2) but nothing with 
pure usb2umass

Maybe (txt_KERNCONF). The usb does not work with the GENERIC kernel.
Concerning /etc/rc.conf I have a usb mouse which does not work with 
moused, so I have in /etc/rc.conf usbd enabled but not moused.

In the archive, there is txt_KERNCONF, txt_panic (the kernel messages 
between the boot and the panic with umass2, it is *only a part* of 
/var/log/messages*) and txt_sysctl_with_umass2.
Note that the kernel build fail with "options udbp" (USB double bulk 
pipe device), without your usb code.

Under 6.0beta4 I have the same panic ie with pure usb2 umass with the 
same KERNCONF file. And the generic kernel also do not allow umass to 
work.

Maybe I can configure a dump device for the kernel panic ? How ?
