--- Comment #13 from Mark Johnston <ma...@freebsd.org> --- In both cases, we crashed in bucket_drain() when resetting bucket->ub_cnt to 0: 0xffffffff80e17d90 <+256>: movslq %r13d,%r13 0xffffffff80e17d93 <+259>: mov 0x18(%rbx,%r13,8),%rdi 0xffffffff80e17d98 <+264>: mov 0x10c(%r14),%esi 0xffffffff80e17d9f <+271>: callq *0xe8(%r14) 0xffffffff80e17da6 <+278>: inc %r13d 0xffffffff80e17da9 <+281>: movswl 0x10(%rbx),%eax 0xffffffff80e17dad <+285>: cmp %eax,%r13d 0xffffffff80e17db0 <+288>: jl 0xffffffff80e17d90 <bucket_cache_drain+256> 0xffffffff80e17db2 <+290>: mov 0x100(%r14),%rdi 0xffffffff80e17db9 <+297>: movswl %ax,%edx 0xffffffff80e17dbc <+300>: mov %r12,%rsi 0xffffffff80e17dbf <+303>: callq *0xf8(%r14) 0xffffffff80e17dc6 <+310>: movw $0x0,0x10(%rbx) <-- rbx is a callee-saved register that is dereferenced after every call to uz_fini, so it seems as though the uz_release function for the zone is somehow corrupting its frame. Because this is happening in the context of uma_reclaim(), we know that this can't be a cache zone, so uz_release is zone_release(). -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
