acpi regression on some laptops

acpi regression on some laptops

[Alessandro Zummo]

 Hello,

   with respect to commit e9e2cdb412412326c4827fc78ba27f410d837e6e 
 and the thread at [1] I just wanted to let you all know that
 the problem is still present :)

 I tried several combo of options, but only acpi=off or acpi=ht
 will let the PC boot.

 I'm trying to debug it.. any help/pointers are appreciated. I dont't
 have a deep knowledge of the subsystems involved.

What options did you try?

  nohpet
  nohz=off
  highres=off

Should be tried in various combinations.

 Hi,

   I tried all the permutations of the above with the same result:
 the kernel hangs at NET: Registering protocol family 2.

 With nolapic it hangs at APIC: Using PIC for interrupt routing

 With acpi=off it boots but, obviously, everything acpi related
 does not work.
 
 anything else I can try? The laptop does not have a serial port,
 so I can't capture the dmesg output.

I'm unsure just what hardware you're working with, but try using the 
option nolapic_timer.

 it worked, thanks!

 hw is a Dell Inspiron 1501, AMD Turion TL52 based.
 drop me a note if you need dmesg or other info.

vendor_id       : AuthenticAMD
cpu family      : 15
model           : 72
model name      : AMD Turion(tm) 64 X2 Mobile Technology TL-52
stepping        : 2

 eax in    eax      ebx      ecx      edx
00000000 00000001 68747541 444d4163 69746e65

What chipset is it? I'm going to guess at nVidia MCP51, in which case.. 
That's the third time that's worked on the MCP51.

Hm, rather different from mine.

Does anyone with a clue want to have a look at this?
