Hi All,
I was running today some kdapltest and after about 10 tests i got this oops.
the test was :
./kdapltest -T T -s 11.1.4.43 -D mthca0a -d -t 2 -w 8 -i 10 client SR server SR
(the same test pass before it got the oops)
my system is :
dual x86 xeon 2G with 1GB memory + suse9.1 + k2.6.11 + svn rev 2546 + kdapl
my kernel is with CONFIG_DEBUG_PAGEALLOC
