It boots, and during booting, around the time it is supposed to initalize serial device and software watchdog, it hangs with a message like this: (Note: It is garbled on my serial terminal): ---- v ((r20t0u1all0 7ad-d0r8e)s ww itt00 0M000N0YY8_ R TSS rSiHnttiREn_gI Reii SS P IAA0L0_PP0000 1I8 E P**Ppddee naabb0l0ed0 0000 ttyS00 at 00 3fCPU: 1 ) is a 0010:[<00000018 0x02f8 (itainted sEFLAGS: 0 010Real Time Clock0000 ebx.10f 6foftware Wat0000001 er: 0.05, timer mesiin: 60 se0 edi: c1b02000 ebp: ffff e000 esp: c1b03fb0 ds: 0018 es: 0018 ss: 0018 Process swapper (pid: 0, stackpage=c1b03000) Stack: c01070a2 00000002 00000000 00000000 00000000 c011f855 00000b1a 00000b1a 00000286 c03ac81c 00000001 00000000 00000001 c044cbea 00000246 0000002a 000000ff c011facf 00000000 00000400 Call Trace: [] [] [] Code: Bad EIP value. <0>Kernel panic: Attempted to kill the idle task! In idle task - not syncing --- If it matters, I am booting this machine with 'acpi=off' as with ACPI enabled, whenever I reboot the machine, It just turns itself off. Cold starting from 2.4 and 2.6 works just fine. The machine runs the ltp test and can compile kernels several times with -j8 Please let me know if you need more information. cheers, Masoud
