Bug#604627: linux-image-2.6.32-5-amd64: megasas: Failed to alloc kernel SGL buffer for IOCTL

[Marc-Christian Petersen <m.c.p@gmx.de>]

Hi all,

latest Squeeze Kernel (2.6.32-39squeeze1, Update avail today) re-introduces
kind the same bug, i.e. smartmontools not usable with megaraid.

smartmontools cannot open the device:

Smartctl open device: /dev/sda [megaraid_disk_01] failed: INQUIRY failed

Smartctl open device: /dev/sg0 [megaraid_disk_00] failed: INQUIRY failed

Kernel 2.6.32-39 (the one before squeeze1) just works.
