Thanks for the explanation George!
Jaroslav - to answer your other question "how can I dump this using the
offset 0x80013000?" you can use the moddump plugin with --base= 0x80013000.

Jaroslav,
Kernel timers come and go at a very high rate which leads to a significant
number of invalid or spurious timer artifacts which result from the fact
that the memory dump was acquired from the system while it was running.
Not that the last two timers are signaled and the periods are not
coherent. It is possible that the last two "timer" objects reside in
memory that once was a kernel timer object and has since been freed and
that some of the timer fields (e.g. the routine address) have been
overwritten with incoherent data. Try running the !pool command on the
last two timer addresses (0x863ead10 and 0x85e451e8) and see if that memory
is currently allocated. (I am assuming that you either have or can convert
your memory dump to MS crashdump format.)
Regards,
George.

Hi all,
I'd like to ask you for your help with analysis. The timers module shows
that there is a strange DPC at 0x8647e4e0.
