If I do a normal boot which includes eata being loaded, the disk attached to the DPT2044W controller having its filesystems checked and mounted, then attempt a kexec reboot, I get the reboot pausing after the "synchronizing SCSI cache" messages as before. If I un-mount the filesystems on the disk attached to the DPT2044W controller after start-up and try a reboot I get the same problem. If I do modprobe -r eata after un-mounting the filesystems on the disk attached to the DPT2044W controller after a start-up kexec *works fine*.Hi Arthur, The above results suggest that we need to shutdown eata controller for kexec. So could you please try to apply the attached patch upon the previous two patches? Thanks! Gerry
To clarify, if the eata driver gets loaded once and stays loaded, at a kexec reboot attempt the "Synchronising SCSI cache" message is missing for the SCSI disk attached to the controller using the eata driver and eventually other error messages appear as seen in screen images that I have previously posted.
If the eata driver is loaded, unloaded via modprobe -r, then reloaded, a kexec reboot shows 2 "Synchronising SCSI cache" messages for the SCSI disk attached to the controller using the eata driver and the kexec reboot is successful.
