The patch titled edac: i5000_edac critical fix panic out of bounds has been removed from the -mm tree. Its filename was edac-i5000_edac-critical-fix-panic-out-of-bounds.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: edac: i5000_edac critical fix panic out of bounds From: Tamas Vincze <tom@xxxxxxxxxx> EDAC MC0: INTERNAL ERROR: channel-b out of range (4 >= 4) Kernel panic - not syncing: EDAC MC0: Uncorrected Error (XEN) Domain 0 crashed: 'noreboot' set - not rebooting. This happens because FERR_NF_FBD bit 28 is not updated on i5000. Due to that, both bits 28 and 29 may be equal to one, returning channel = 3. As this value is invalid, EDAC core generates the panic.
