Oops in 2.6.37-rc{3,4,5}
I'm not subscribed, so please cc me on any reply.
With rc kernels from 2.6.37, X frequently (approx 3 boots out of every 4) fails to start. dmesg shows the oops below. I can bisect over the weekend - probably Sunday - if no answer comes up in the meantime. I get the same oops with rc3, rc and rc5. rc2 doesn't get as far as trying to start X. Happy to test patches or provide additional diagnostics, but I'll be off line soon until 20:00 or so UK time tomorrow.
