linux syscall get_robust_list causes panic

hi there,

i tried to run the latest release (20090531) of the linux test project (ltp)
with emulators/linux_dist-gentoo-stage3. however the kernel panics after ltp's
get_robust_list(2) test. set_robust_list(2) passes without any problems.

i've attached a screenshot of the panic and the source which is causing the
panic. you won't be able to compile it without ltp however. after installing
and compiling ltp the source and the executable can be found in
"/usr/local/gentoo-stage3/ltp-full-20090531/testcases/kernel/syscalls/get_robust_list".
simply running the
"/usr/local/gentoo-stage3/ltp-full-20090531/testcases/kernel/syscalls/get_robust_list/get_robust_list01"
executable results in a panic.

unfortunately i cannot supply a complete bt, because i only own a usb keyboard
which doesn't respond after the panic. actually i'm a bit surprised the
debugger was started, because i have "KDB_UNATTENDED" in my kernel conf. any
reason the machine doesn't reboot and save the dump to /var/crash/vmcore.*?

i'm running r193846 (CURRENT).

cheers.
