Steps to reproduce:


Unable to resume from S3 in Fedora linux 2.6.15.  while going to sleep(s3)  
the firmware wake vector should be filled by OS (linux). but in our case it is 
not filled (value 0)

Comment 1 Diego Calleja 2006-10-09 10:41:13 UTC

Can you tell if this problem is still in 2.6.18? 2.6.15 is kinda old with the
current development speed

Comment 2 mugilan 2006-10-10 07:55:34 UTC

ya, i am facing the problem in 2.6.18 kernel version also

Comment 3 mugilan 2006-11-02 00:00:22 UTC


When i debugged the kernel using kdb, i stopped inside the 
function "acpi_set_firmware_waking_vector" in "\linux-2.6.16.13
\drivers\acpi\hardware". i can able the assembly code, i have an istruction.
mov ecx,dword ptr [0xc1312800]. i am using only 256 ram.
 
this is virtual addrss. can anyone tell me how should i calculate the 
physcial  address of that corresponding virt address.

Actually the Waking_vector_address is filled in this function by OS. 
Its getting filled in Virtual address. But when i saw the physical address 
corresponding to that virtual address, its not get filled. Could any one 
suggest how to proceed next..

Is this still a problem in linux-2.6.22.stable or later?

Comment 5 Adrian Bunk 2007-10-06 14:23:22 UTC

Please reopen this bug if it's still present with kernel 2.6.22.
