the hardware is an ordinary amd sempron processor. I rebuilt all the stuff.
Particularly glibc. configured with --enable-kernel=2.6.18.
Still having the old error. I used strace to trace it, as I had been advised.
3 processes are started. the 3rd is created by the second, and the 2nd by the
1st.
the problem is with the 3rd and strace reveals this:
futex(0xb7ee5004, 0x100 /* FUTEX_??? */, 2, {1244666445, 178371000}) = -1
ENOSYS (Function not implemented)
in the last trace file.
By the time writing this, linux-2.6.30 has been released. I restart all the
build with it.
