While bisecting a dri S3 issue I stumbled in 2.6.38-rc1 over a regression because of NX protection (5bd5a4, currently being discussed), and with a patch fixing this issue I stumbled again in 2.6.38-rc2 because of commit bd924e8:

smp: Allow on_each_cpu() to be called while early_boot_irqs_disabled status to init/main.c

Reverting this commit makes suspend work on SandyBridge again. I haven't tested reverting this commit on v2.6.38-rc2 yet, though.

I'm compiling for i586, not x86_64.

lspci -vvv output is attached.

(for internal reference: machine NUE874)

The patch in https://bugzilla.kernel.org/show_bug.cgi?id=27472#c9 fixes both regressions.
