hm, one difference is that i'm running a 64-bit kernel but 32-bit
userspace (FC3-ish).
Yes, that's it! I've just successfully booted into 32-bit userspace (I
have a separate partition with old 32-bit Debian) with x86_64 kernel and
LATENCY_TRACE enabled. Everything seemed to work.
Then I mounted my normal root partition under /mnt/64 and tried
chroot /mnt/64
I got a SIGSEGV. Then I copied some simple binaries from /mnt/64/bin to
/root/test/bin and some necessary libraries to /root/test/lib and did
chroot /root/test
I could run 64-bit sash, ls, cat, date, mkdir - it worked. 64-bit bash
however segfaulted.
