As discussed in the bugzilla outlined below, we have an sa based (Mustang) RAID adapter on the system, a Dell PERC2/QC. Affected controllers are HP NetRAID, Adaptec AAC-364, Dell PERC2/QC or Adaptec 5400S. This problem coincides with the introduction of the adapter_comm and adapter_deliver platform functions (Message [PATCH 1/4] aacraid: rework communication support code, January 23 2007, which initially migrated to 2.6.21) The panic occurs with an uninitialized adapter_deliver platform function pointer. The enclosed patch, unmodified as tested by Rainer, solves the problem. This attached patch is against current scsi-misc-2.6, applies cleanly to 2.6.21-git12. It may require manual intervention to be applied to 2.6.21 or 2.6.21.1, simple breakage when merely adding a single line to aacraid.h: . . . + int aac_rx_deliver_producer(struct fib * fib); extern int numacb; . . .
