Hello! I'm using Linux (kernel 2.6.2-rc3) on my Samsung X10 (Pentium M 1.4 GHz, Centrino) notebook. If I boot the system without ac-adapter connected and then modprobe the module processor the notebook makes a really silly noise. The noise disappears with load (i.e.starting a program) but reappears as soon as the processor ist idle again. Plugging in the ac-adapter fixes the problem. Disconnecting the adapter is no problem. Scaling down cpu-frequency makes the noise quiete, but it still resists. rmmod processor brings an oops: Oops: 0000 [#1] CPU: 0 EIP: 0060:[<e1cdf28f>] Tainted: P EFLAGS: 00010296 EIP is at 0xe1cdf28f eax: 00000000 ebx: 001bdf10 ecx: 00000008 edx: 00000000 esi: d36f92f8 edi: 001bd989 ebp: d36f9200 esp: c04c5fc0 ds: 007b es: 007b ss: 0068 Process swapper (pid: 0, threadinfo=c04c4000 task=c043a6e0) Stack: 00099800 00000000 c04c4000 00099800 c0105000 0008e000 c0108a04 00000816 c04c6745 c043a6e0 00000000 c04e77e8 0000001b c04c6470 c04ef020 c010017e Call Trace: [<c0105000>] _stext+0x0/0x60 [<c0108a04>] cpu_idle+0x34/0x40 [<c04c6745>] start_kernel+0x185/0x1c0 [<c04c6470>] unknown_bootoption+0x0/0x120 Code: Bad EIP value. <0>Kernel panic: Attempted to kill the idle task! In idle task - not syncing Same behavior with 2.6.2-rc2 before the acpi update. With 2.6.2-rc2-mm1 the noise still resists if I plug in the ac-adapter. Let me know if you need additional information.
