"rm -rf" stuck on pandaboard

[Dennis.Yxun]

Hi ALL:
   I'm running Gentoo on pandaboard, and doing pretty much heavy compiling
The problem here I meet is that after compile a few time, rm -rf /var/tmp/portage/xxfile
got choked, here top command shows, CPU running 100:
17274 root      20   0  3800  620  472 R  100  0.1  75:39.92 rm 
and kill -9 17274 won't help

More detail of what I'm doing
0) using usb-storage device as my root  (yes, mount  /dev/sda2 to / )

1) mount /var/tmp/portage as tmpfs,
tmpfs  /var/tmp/portage  tmpfs rw,size=1200M,nr_inodes=1M 0 0

2) using swap file
/swapfile               none            swap            sw              0 0

3) using kernel from git://git.linaro.org/people/andygreen/kernel-tilt.git
commit 5b14e370cca884fa86471e909512f65b06dcaec2

4) kernel command paramater
[    0.000000] Kernel command line: ro elevator=noop vram=32M root=/dev/sda2 rootwait fixrtc console=ttyO2,115200 mem=456M@0x80000000 mem=512M@0xA0000000

Any suggestion? or any other info needed?

Dennis

when it hang again do "echo t >/proc/sysrq-trigger" then check dmesg
and look for the hanging rm process. the stacktrace may give a clue
as to what's wrong.
