Sorry to disappoint you. That 3.4.1-1~experimental.1 build
(3.4-trunk-686-pae #1 SMP Wed Jun 6 15:11:31 UTC 2012 i686 GNU/Linux)
is even less well-behaved under Xen: I'm getting a kernel OOPS at
EIP: [<c1168e54>] atomic64_read_cx8+0x4/0xc SS:ESP e021:ca853c6c
The top of the trace message unfortunately scrolled off the console before I
could see it, and the message doesn't have time to make it to syslog (either
local or remote).
An interesting twist: the trace is timestamped 0.776065 but there is exactly
one more message on the console at 1.344071 before the system hangs:
Refined TSC clocksource calibration: 3191.999 MHz.
(This is indeed a 3.2 GHz CPU.)
Non-Xen boots proceed normally.
Feel free to split this bug report since this new OOPS is clearly unrelated
to the nouveau issue (it happens even when the nouveau module is blacklisted);
I only mention it here because it's preventing me from checking whether the
problem with nouveau is still present.
