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.
