I investigated this problem.
The problem was that Segate 80GB HDD (ST380020ACE) erroneously has 48bit LBA turned on,
but the capacity field for 48Bit LBA has 0.
So, i modified the "init_idedisk_capacity()" function to forcily use the 28bit LBA mode
in this case. I know that the HDD less than 137GB no need to use 48bit LBA.

If there is someone who suffers from the same symptom, try the following patch at your own risk. ^^;;;

Subject: Kernel Panic 2.4.19 with Segate 80GB HDD

Quoted 9 lines

I used kernel 2.4.19 with Segate 80GB HDD (ST380020ACE).
The kernel could not recognize the number of sectors correctly, and then result in kernel panic.
I tried kernel 2.4.18 with the same HDD, there is no problem.

Is this a bug in the ide device driver ? or is there any compatible HDD list for 2.4.19 kernel ?

#1 lore raw

No "erroneously has 48bit LBA turned on" is not what is happening. There are general purpose logs which reqire 48-bit operations. A device can support 48-bit command and be less than 137GB. Also if you disable 48-bit some of the drive features will not work.

Bit on and zero in words 100-103 is a Buggy SPEC!

Currently an beautiful mess has been made by the committe.

If device supports 48-bit is it required to report capacity in all 48-bit locations in the IDENTIFY Page?

If the device is destroked to less than 137GB does it report the same in both words 60-61 and 100-103?

There are worse yet to come.

I investigated this problem.
The problem was that Segate 80GB HDD (ST380020ACE) erroneously has 48bit LBA turned on,
but the capacity field for 48Bit LBA has 0.
So, i modified the "init_idedisk_capacity()" function to forcily use the 28bit LBA mode
in this case. I know that the HDD less than 137GB no need to use 48bit LBA.

If there is someone who suffers from the same symptom, try the following patch at your own risk. ^^;;;

I used kernel 2.4.19 with Segate 80GB HDD (ST380020ACE).
The kernel could not recognize the number of sectors correctly, and then result in kernel panic.
I tried kernel 2.4.18 with the same HDD, there is no problem.

Is this a bug in the ide device driver ? or is there any compatible HDD list for 2.4.19 kernel ?

#2 lore raw

I am sorry that i have little knowledge on the spec. related to IDE. The statement of "erroneously has 48bit LBA turned on" was made based on the original code and the following experiment.
When i copied "id->lba_capacity" to "id->lba_capacity_2" with maintaining 48bit LBA
in case that id->lba_capacity_2 (100-103th byte in ID) was zero, I could not access the HDD correctly and i got always "DriveStatusError". So i assumed Seagate80GB HDD does not support 48bit LBA properly. I inserted the following code at the very first part of the "init_idedisk_capacity()" function at the experiment.

if (id->cfs_enable_2 & 0x0400) {
      if (id->lba_capacity_2 == (long long) 0)

             id->lba_capacity_2 = id->lba_capacity;
      }
}

p.s.
Anyway it is my pleasure i can talk to you.
I always thank you for what you have done related to the IDE stuff.

No "erroneously has 48bit LBA turned on" is not what is happening. There are general purpose logs which reqire 48-bit operations. A device can support 48-bit command and be less than 137GB. Also if you disable 48-bit some of the drive features will not work.

Bit on and zero in words 100-103 is a Buggy SPEC!

Currently an beautiful mess has been made by the committe.

If device supports 48-bit is it required to report capacity in all 48-bit locations in the IDENTIFY Page?

Quoted 11 lines

If the device is destroked to less than 137GB does it report the same in both words 60-61 and 100-103?

There are worse yet to come.

I investigated this problem.
The problem was that Segate 80GB HDD (ST380020ACE) erroneously has 48bit

LBA

Quoted 5 lines
Quoted 5 lines

turned on,
but the capacity field for 48Bit LBA has 0.
So, i modified the "init_idedisk_capacity()" function to forcily use the 28bit LBA mode
in this case. I know that the HDD less than 137GB no need to use 48bit

LBA.
