I'm suspecting a problem in the reporting scripts. The patch had:
From: Stas Sergeev <stsp@aknet.ru>
Attached patch works around the corruption of the high word of the ESP
register, which is the official bug of x86 CPUs. The bug triggers only

From: Oleg Nesterov <oleg@tv-sign.ru>
I think that Stas tries to steal 1024 bytes from kernel's memory.
