Thank you, Hans.
One additional bit, may be it's about different problem.
While copying from reiser4 volumes to newly created ext3 ones, I decided
to remount read-only the with "mount -o remount,ro" command the source
of copying.
And it results in kernel panics I'm attaching to this mail.
Then the cp process become unkillable, and the system did not reboot
down remotely, I'll see at which point it hanged when I'll be there.
