https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D219153 --- Comment #18 from Mark Millard <marklmi26-fbsd@yahoo.com> --- (In reply to Leandro Lupori from comment #17) I tried a 2-socket PowerMac G4 (head -r358510) and, for a minidump, after reboot . . . GNU gdb (GDB) 8.3.1 [GDB v8.3.1 for FreeBSD] got: inferior.c:287: internal-error: struct inferior *find_inferior_pid(int): Assertion `pid !=3D 0' failed. A problem internal to GDB has been detected, further debugging may prove unreliable. Quit this debugging session? (y or n) y (I've seen reports with such for other platforms in the past.) By contrast, GNU gdb 6.1.1 [FreeBSD] got: kgdb: kvm_read:=20 No symbol "zombproc" in current context. 0x00000000 in ?? () (kgdb) bt #0 0x00000000 in ?? () (Not so useful.) Attempting a non-minidump hung up during the dump, much like for powerpc64. (I did have to make the dump partition be somewhat bigger than 2048 MiBytes to prevent being told that it was too small.) I used to be able to make such dumps under 32-bit powerpc FreeBSD. But it has been a long time since I've tried such so I've no clue when it stopped being able to write such dumps. (Analyzing them had its own issues.) I'm not so sure that the current G4 behavior should be classified with this submittal. I'll leave it to you if you want this submittal closed in some way. Most of the information is probably too old to be of much use for going forwards as far as old PowerMacs go. --=20 You are receiving this mail because: You are the assignee for the bug.=
