Hi
Kernel 3.6-rc3 does not boot for me with netconsole enabled, while 3.6-rc2 did.
I bisected it to commit 6bdb7fe31046ac50b47e83c35cd6c6b6160a475d "netpoll:
re-enable irq in poll_napi()" and reverting it on top of current Linus' tree
restores proper behaviour (disabling netconsole does this too).
"Not booting" manifests as immediate hang after network card enabling.
Cheers,
Marcin
