Hi all,

Hi,

Quoted 9 lines

The IRQ should be disabled somewhere in the path walk, which makes the GFP_KERNEL allocation in uart_startup() no longer valid..

This does not make sense to me. I would not blame TTY/serial for this. There is somebody who forgot to enable interrupts somewhere. Could you enable DEBUG_ATOMIC_SLEEP? It might trigger earlier revealing us the culprit.

thanks,

Jiri, thanks for the info. After turning on DEBUG_ATOMIC_SLEEP, this shows up which I just reported in another email. Ah I didn't notice that it's running the same commit "x86: switch to generic sys_execve and kernel_execve"..

That'd be me, I'm afraid. With changes in signal.git#execve2 we need to set ->flags in start_thread() on i386 as well, not only on amd64 (where we were already doing that). Incremental follows, fix folded and repushed...
