Hi,

FreeBSD DomU details:
FreeBSD 8.2-RELEASE (XEN) i386

The kernel was compiled as
# make buildkernel KERNCONF=XEN INSTKERNNAME=8.2-XEN

The CVS brach used is:
RELENG_8_2



I got kernel panics while was compiling GHC from ports:

===>  Configuring for hs-ghc-paths-0.1.0.5_1
[1 of 1] Compiling Main             ( Setup.hs, Setup.o )
Linking setup ...
gcc: Internal error: Killed: 9 (program ld)
Please submit a full bug report.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
*** Error code 1


The panic details are (from main console):

lock order reversal:
 1st 0xc05b08c4 PMAP2 (PMAP2) @ /usr/src/sys/i386/xen/pmap.c:1049
 2nd 0xc054de04 vm page queue mutex (vm page queue mutex) @
