--- Comment #4 from Mark Millard <[email protected]> --- (In reply to Mark Millard from comment #3) Based on register values values it looks like the openfirmware code got something like, say, a Data Storage Exception, that in turn went to generictrap, that in turn went to k_trap: <k_trap> mfsprg r31,0 <k_trap+0x4> mfsrr0 r30 <k_trap+0x8> std r30,288(r31) <k_trap+0xc> mfsrr1 r30 <k_trap+0x10> std r30,296(r31) <k_trap+0x14> mfsprg r31,1 <k_trap+0x18> mfmsr r30 <k_trap+0x1c> ori r30,r30,50 <k_trap+0x20> mtmsr r30 <k_trap+0x24> isync <k_trap+0x28> stdu r31,-688(r1) It failed at the last because the value r1 held 0xffff'ffff'ffb7'f400, apparently an openfirmware stack address being handled by a FreeBSD exception handler under the FreeBSD memory management. (So far, I can not be sure of what, specifically, initiated getting to k_trap.) -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
