Jan,
in 2.6.19-rc6 i'm getting frequent unwinder failures, like:
[<c0104eb5>] dump_trace+0x69/0x1b0 [<c0105013>] show_trace_log_lvl+0x17/0x2b [<c034e6c4>] __func__.18297+0xf3fd/0x3ccf5 DWARF2 unwinder stuck at __func__.18297+0xf3fd/0x3ccf5
Leftover inexact backtrace:
[<c010534b>] show_trace+0xf/0x11 [<c0105360>] dump_stack+0x13/0x15 [<c01419e9>] __lock_acquire+0x6fe/0x98a [<c0175956>] cache_alloc_refill+0x8f/0x534 [<c0141f14>] lock_acquire+0x5b/0x77 [<f0a32963>] __ip_ct_refresh_acct+0x123/0x15b [ip_conntrack] [<f0a32963>] __ip_ct_refresh_acct+0x123/0x15b [ip_conntrack] [<f0a34acc>] udp_packet+0x9e/0xaa [ip_conntrack] [<f0a33437>] ip_conntrack_in+0x385/0x479 [ip_conntrack] [<c01215d8>] try_to_wake_up+0x3ea/0x3f4 [<c0324300>] netlbl_mgmt_listall_cb+0xc8/0x1bd [<c02dfe28>] nf_iterate+0x38/0x6a [<c02e4dbf>] ip_rcv_finish+0x0/0x271 [<c02dfeac>] nf_hook_slow+0x52/0xc9 [<c02e4dbf>] ip_rcv_finish+0x0/0x271 [<c02e564f>] ip_rcv+0x1fc/0x491 [<c02e4dbf>] ip_rcv_finish+0x0/0x271 [<c02c1f2a>] sock_queue_rcv_skb+0xd5/0xdc [<c02e5453>] ip_rcv+0x0/0x491 [<c02cac42>] netif_receive_skb+0x339/0x366 [<c02cad04>] process_backlog+0x95/0xed [<c02c909e>] net_rx_action+0xad/0x1da [<c012bfdc>] ksoftirqd+0x107/0x1e0 [<c012bed5>] ksoftirqd+0x0/0x1e0 [<c0139520>] kthread+0xbf/0xeb [<c0139461>] kthread+0x0/0xeb [<c0104c23>] kernel_thread_helper+0x7/0x10 =======================
it's quite an annoyance, i rarely see the unwinder getting a stackdump right, without 'falling back' to the inexact backtrace ...
