Not that simple. The .shutdown would need to perform more resource cleanups of the .remove call to prevent side effects. I need to move some of the .remove activity into the .shutdown handler to make sure the adapter is quiesced. I will hold off on submitting any of these changes until they are evaluated and tested; I am waiting for feedback from Yinghai on the other mitigations that I feel are closer to the root cause.
1. [SCSI] aacraid: superfluous adapter reset for IBM 8 series ServeRAID controllers 2. [SCSI] aacraid: kexec fix (reset interrupt handler) 3. aacraid_commit_reset.patch 4. [PATCH] aacraid: fix shutdown handler to also disable interrupts the kernel with this patch -4 and even without 1, 2, 3 can load other kernel with or without patch 1,2,3 YH - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
