I've just started digging into the innards of the s3fb driver, my first attempt provoked this, simply by commenting out the check to see if it's not the primary device and exits with -ENODEV: Jan 3 20:16:29 sodium kernel: ERROR(1): Cheetah error trap taken afsr[0030100000000000] afar[00000000000003d0] TL1(0) Jan 3 20:16:29 sodium kernel: ERROR(1): TPC[105918d8] TNPC[105918dc] O7[10591884] TSTATE[4411001606] Jan 3 20:16:29 sodium kernel: ERROR(1): TPC Jan 3 20:16:29 sodium kernel: ERROR(1): M_SYND(0), E_SYND(0), Multiple Errors, Privileged Jan 3 20:16:29 sodium kernel: ERROR(1): Highest priority error (0000100000000000) "Unmapped error from system bus" Jan 3 20:16:29 sodium kernel: ERROR(1): D-cache idx[0] tag[0000000000000000] utag[0000000000000000] stag[0000000000000000] Jan 3 20:16:29 sodium kernel: ERROR(1): D-cache data0[0000000000000000] data1[0000000000000000] data2[0000000000000000] data3[0000000000000000] Jan 3 20:16:29 sodium kernel: ERROR(1): I-cache idx[0] tag[0000000000000000] utag[0000000000000000] stag[0000000000000000] u[0000000000000000] l[0000000000000000] Jan 3 20:16:29 sodium kernel: ERROR(1): I-cache INSN0[0000000000000000] INSN1[0000000000000000] INSN2[0000000000000000] INSN3[0000000000000000] Jan 3 20:16:29 sodium kernel: ERROR(1): I-cache INSN4[0000000000000000] INSN5[0000000000000000] INSN6[0000000000000000] INSN7[0000000000000000] Jan 3 20:16:29 sodium kernel: ERROR(1): E-cache idx[3c0] tag[000000000b040000] Jan 3 20:16:29 sodium kernel: ERROR(1): E-cache data0[000c5aa000000011] data1[000f43d800000040] data2[0000000000000109] data3[0000000000000000] Jan 3 20:16:29 sodium kernel: Kernel panic - not syncing: Irrecoverable deferred error trap.
