When exiting suspend mode on hp6735s with bios revision F0D the fan goes at maximum speed and doesn't slow down until the machine is restarted. In the dmesg log this report appears: [13958.610704] WARNING: at /build/buildd/linux-2.6.28/kernel/power/main.c:177 suspend_test_finish+0x80/0x90() [13958.610706] Component: suspend devices [13958.610707] Modules linked in: mt2060 dvb_usb_af9005_remote dvb_usb_af9005 dvb_usb dvb_core usbhid binfmt_misc ppdev lp parport bridge stp bnep input_polldev ipt_REJECT ipt_LOG xt_limit xt_tcpudp xt_state ipt_addrtype ip6table_filter ip6_tables nf_nat_irc nf_conntrack_irc nf_nat_ftp nf_nat nf_conntrack_ipv4 nf_defrag_ipv4 nf_conntrack_ftp nf_conntrack iptable_filter ip_tables x_tables adm1021 k8temp acpiphp snd_hda_intel snd_pcm_oss snd_mixer_oss snd_pcm snd_seq_dummy snd_seq_oss snd_seq_midi snd_rawmidi snd_seq_midi_event snd_seq snd_timer snd_seq_device fglrx(P) joydev leds_hp_disk led_class snd soundcore i2c_piix4 agpgart psmouse serio_raw snd_page_alloc ieee80211_crypt_tkip pcspkr video lis3lv02d wl(P) ieee80211_crypt output shpchp reiserfs sky2 fbcon tileblit font bitblit softcursor [13958.610743] Pid: 11204, comm: pm-suspend Tainted: P 2.6.28-15-generic #52-Ubuntu [13958.610745] Call Trace: [13958.610750] [] warn_slowpath+0x60/0x80 [13958.610754] [] ? down_trylock+0x2a/0x40 [13958.610757] [] ? try_acquire_console_sem+0xd/0x30 [13958.610762] [] ? kobject_put+0x20/0x50 [13958.610768] [] ? printk+0x18/0x1a [13958.610770] [] suspend_test_finish+0x80/0x90 [13958.610773] [] suspend_devices_and_enter+0x65/0x160 [13958.610776] [] ? printk+0x18/0x1a [13958.610779] [] enter_state+0xc9/0x100 [13958.610781] [] state_store+0x7d/0xc0 [13958.610784] [] ? state_store+0x0/0xc0 [13958.610787] [] kobj_attr_store+0x24/0x30 [13958.610790] [] sysfs_write_file+0x92/0xf0 [13958.610795] [] vfs_write+0x98/0x110 [13958.610797] [] ? sysfs_write_file+0x0/0xf0 [13958.610800] [] sys_write+0x3d/0x70 [13958.610803] [] sysenter_do_call+0x12/0x2f Moreover, if the system is suspended a second time, the fan stops at all and doesn't restart again, forcing to reboot the machine.
