 ! please show us the panic and a backtrace. Also please include the
 ! config modifications you're using (a diff would be fine).
 Here is the panic and backtrace:

 Now for a config diff, the problem is that my config is inherited
 (since RELEASE_2.1.0 - as the whole machine is just growing and
 never full replaced) - it isn't similar in sequence to today's 
 And as I mentioned, I have tried to boot GENERIC and there the panic
 does happen equally. 
 I didn't send the PR from GENERIC, because I essentially consider 
 it harmful to boot GENERIC to anywhere beyond singleuser; and anyway
 it is impossible to get debugging information from GENERIC since
 in case of a panic it overfills the screen and then just freezes 
 and waits for a hard powercycle.
 This is what remains on the screen in that case:
 >frame pointer           = 0x28:0xcbfe2cec
 >code segment            = base 0x0, limit 0xfffff, type 0x1b
 >                        = DPL 0, pres 1, def32 1, gran 1
 >processor eflags        = interrupt enabled, resume, IOPL = 0
 >current process         = 30 (irq11: ed0)
 >trap number             = 12
 >panic: page fault
 >Uptime: 8m15s
 >kernel trap 12 with interrupts disabled
 >Fatal trap 12: page fault while in kernel mode
 >fault virtual address   = 0x7010
 >fault code              = supervisor read, page not present
 >instruction pointer     = 0x20:0xc06b15ed
 >stack pointer           = 0x28:0xcbfe27d0
 >frame pointer           = 0x28:0xcbfe27d8
 >code segment            = base 0x0, limit 0xfffff, type 0x1b

 Anyway, here is some sorted diff between GENERIC and my custom

 Further, here are the modifications in /boot:
 I should also mention that I already have done these steps: 
  - reboot the old OS version and check if it still works there,
    to rule out a sudden hw failure.
  - try "minimal config": remove all add-on hardware except the
    failing part. 
 The board itself is an ASUS P2B, and the bootlog can be sent to
 interested investigators, but will not be published, for security
