It appears to be impossible to get a SysRQ-T dump out of a kernel which has hung during (eg) the SCSI initialisation with 2.5.
Unlike previous 2.4 kernels, the keyboard is no longer initialised until fairly late - after many of the other drivers have initialised. Unfortunately, this means that it is quite difficult to debug these hangs (we'll leave discussion about in-kernel debuggers for another time!)
Can we initialise the input subsystem earlier (eg, after pci bus initialisation, before disks etc) so that we do have the ability to use the SysRQ features?
