usb-storage oopsed.  That killed keventd and the keyboard needs keventd
services.

Is this a scsi bug or a USB bug?

> Is this a scsi bug or a USB bug?

How can i chek it. If i'll disable scsi my sata vill never boot.

It's really difficult to work with this hardware. I compiled kernel with
ub and usual support and kernel oopsed and friezed on boot without any
attached usb device. I tryed kernel without module_autoloading and after
i loaded usb-storge module its oopsed too. How can i patch kernel
selectively without new scsi or usb patches? i think it's can be scsi
problem.

dmesg+debug

I houp this dmesg help you. The kernel is compiled with scsi,usb,kernel debug
options.

Since the oops occurs inside scsi_target_reap_work, this looks like a SCSI bug.
 It should be reassigned.
