An out of memory failure during a sg device open
means the kernel couldn't find 4 KB . [Sg reduces
the requested reserved size buffer until the kernel
gets some memory or the size is <= 4KB.] This is
horrible. Sounds as if that usb-scsi patch has
'unchecked_isa_dma' set to 1 thus restricting sg to
getting memory below the 16 MB level.
Just checked the usb-scsi code and that is not the case.
Have you any idea why there would be such a shortage
of memory on your machine? If you have CONFIG_MAGIC_SYSRQ
selected in your kernel, what does Alt+SysRq+M output?
