Looking at http://www.spinics.net/lists/sparclinux/msg05073.html, I've also experienced this problem with 2.6.24 kernel. Problem occurred during high CPU/memory usage, on two machines (Sun Fire V240), so I would exclude problems with RAM. Info from one of them: Jun 30 22:59:15 udruge kernel: [826466.100818] ERROR(0): Cheetah error trap taken afsr[0010100000000000] afar[0000000040000000] TL1(0) Jun 30 22:59:15 udruge kernel: [826466.100839] ERROR(0): TPC[407c70] TNPC[407c74] O7[456738] TSTATE[411f09603] Jun 30 22:59:15 udruge kernel: [826466.100845] ERROR(0): TPC<copy_tsb+0x38/0x80> Jun 30 22:59:15 udruge kernel: [826466.100862] ERROR(0): M_SYND(0), E_SYND(0), Privileged Jun 30 22:59:15 udruge kernel: [826466.100869] ERROR(0): Highest priority error (0000100000000000) "Unmapped error from system bus" Jun 30 22:59:15 udruge kernel: [826466.100875] ERROR(0): D-cache idx[0] tag[0000000000000000] utag[0000000000000000] stag[0000000000000000] Jun 30 22:59:15 udruge kernel: [826466.100882] ERROR(0): D-cache data0[0000000000000000] data1[0000000000000000] data2[0000000000000000] data3[0000000000000000] Jun 30 22:59:15 udruge kernel: [826466.100889] ERROR(0): I-cache idx[0] tag[0000000000000000] utag[0000000000000000] stag[0000000000000000] u[0000000000000000] l[0000000000000000] Jun 30 22:59:15 udruge kernel: [826466.100896] ERROR(0): I-cache INSN0[0000000000000000] INSN1[0000000000000000] INSN2[0000000000000000] INSN3[0000000000000000] Jun 30 22:59:15 udruge kernel: [826466.100903] ERROR(0): I-cache INSN4[0000000000000000] INSN5[0000000000000000] INSN6[0000000000000000] INSN7[0000000000000000] Jun 30 22:59:15 udruge kernel: [826466.100910] ERROR(0): E-cache idx[40000000] tag[0000000012040ab1] Jun 30 22:59:15 udruge kernel: [826466.100915] ERROR(0): E-cache data0[a204400da2044001] data1[03216117821061d1] data2[9b2c600fb4068001] data3[a33460119a134011] Jun 30 22:59:15 udruge kernel: [826466.100923] Kernel panic - not syncing: Irrecoverable deferred error trap.
