Function store_tolerance() is not called by w83627ehf_probe(). I wouldn't rule out a stack corruption. If there is a debug kernel flavor available for your system, please try it and see if you get a better call trace. > > [ 237.889708] [<ffffffffa0c7c2e4>] ? w83627ehf_probe+0x59e/0x22ba [w83627ehf] Can you please ask gdb which line of the function this is? You'll probably have to install some kernel debugging package for this, don't know how this works on Ubuntu. $ gdb (gdb) file drivers/hwmon/w83627ehf.ko (gdb) list *(w83627ehf_probe+0x59e) > > [ 237.889713] [<ffffffff81057179>] try_to_wake_up+0x39/0x200 > > [ 237.889716] [<ffffffff81057340>] ? try_to_wake_up+0x200/0x200 > > [ 237.889721] [<ffffffff8109ffde>] ? sys_init_module+0x1be/0x230 > > [ 237.889724] [<ffffffff81057375>] wake_up_process+0x15/0x20 > > [ 237.889727] [<ffffffff8109d37f>] module_put+0xaf/0xc0 > > [ 237.889731] [<ffffffff8109ffde>] sys_init_module+0x1be/0x230 > > [ 237.889735] [<ffffffff815fa1c2>] system_call_fastpath+0x16/0x1b > > [ 237.889738] Code: 00 00 48 c7 c1 21 27 03 81 48 c7 c2 1e 27 03 81 > > e9 dd fe ff ff 90 90 90 90 90 90 90 90 90 90 90 90 90 55 b8 00 00 01 > > 00 48 89 e5 <f0> 0f c1 07 0f b7 d0 c1 e8 10 39 c2 74 07 f3 90 0f b7 17 > > eb f5 > > [ 237.889773] RIP [<ffffffff81032919>] __ticket_spin_lock+0x9/0x20 > > [ 237.889777] RSP <ffff8803ea889e68> > > [ 237.889779] CR2: ffffffffa0c7c2e4 > > [ 237.889782] ---[ end trace 99e0d80bf6a60138 ]--- > > > > > > > Also, do you see that the driver is loaded when > > > running "lsmod" ? > > > > no the driver is not loaded This is expected, as loading the driver called the probe() function which never finished.
