Summary: cpu scaling fails, locked on lowest setting at all times https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=205305 ------- Additional Comments From [EMAIL PROTECTED] 2006-09-22 10:33 EST ------- This is defintely happening for me on an Intel Pentium M laptop. The system has been up for 1:20 and CPU scaling was working for some part of that time. dmesg does show this kernel error (seems unrelated though): ============================================= [ INFO: possible recursive locking detected ] 2.6.17-1.2647.fc6 #1 --------------------------------------------- java/3787 is trying to acquire lock: (slock-AF_INET6){-+..}, at: [<c05b392e>] sk_clone+0xd4/0x2d8 but task is already holding lock: (slock-AF_INET6){-+..}, at: [<f8b1d4c9>] tcp_v6_rcv+0x327/0x736 [ipv6] other info that might help us debug this: 1 lock held by java/3787: #0: (slock-AF_INET6){-+..}, at: [<f8b1d4c9>] tcp_v6_rcv+0x327/0x736 [ipv6] stack backtrace: [<c04051ee>] show_trace_log_lvl+0x58/0x171 [<c0405802>] show_trace+0xd/0x10 [<c040591b>] dump_stack+0x19/0x1b [<c043b9e1>] __lock_acquire+0x778/0x99c [<c043c176>] lock_acquire+0x4b/0x6d [<c061539b>] _spin_lock+0x19/0x28 [<c05b392e>] sk_clone+0xd4/0x2d8 [<c05dc49b>] inet_csk_clone+0xf/0x72 [<c05ed2d9>] tcp_create_openreq_child+0x1b/0x3a1 [<f8b1c155>] tcp_v6_syn_recv_sock+0x271/0x5b3 [ipv6] [<c05ed834>] tcp_check_req+0x1d5/0x2e9 [<f8b1b441>] tcp_v6_do_rcv+0x142/0x340 [ipv6] [<f8b1d883>] tcp_v6_rcv+0x6e1/0x736 [ipv6] [<f8b03a6f>] ip6_input+0x1c3/0x296 [ipv6] [<f8b03fdf>] ipv6_rcv+0x1d2/0x21f [ipv6] [<c05b9ab6>] netif_receive_skb+0x2e2/0x366 [<c05bb42f>] process_backlog+0x99/0xfa [<c05bb612>] net_rx_action+0x9d/0x196 [<c04293bf>] __do_softirq+0x78/0xf2 [<c040668b>] do_softirq+0x5a/0xbe [<c04291b6>] local_bh_enable_ip+0xa9/0xcf [<c0615339>] _spin_unlock_bh+0x25/0x28 [<c05b272f>] release_sock+0xb0/0xb8 [<c05f5552>] inet_stream_connect+0x113/0x206 [<c05b1692>] sys_connect+0x67/0x84 [<c05b1d04>] sys_socketcall+0x8c/0x186 [<c0403faf>] syscall_call+0x7/0xb DWARF2 unwinder stuck at syscall_call+0x7/0xb Leftover inexact backtrace: I'm going to reboot with the cpufreq.debug=7 and see if that will reveal more. -- Configure bugmail: https://bugzilla.redhat.com/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------------------------- Take Surveys.
