Hi, I met a problem that sata driver fails to work after resume from S3. The kernel version is 2.6.16.33. After resume from S3, I got the following messages: First, "ATA: abnormal status 0x80 on port 0x1F7" for 3 times. Then, "sd 0:0:0(sometimes is 1):0: SCSI error: return code=0x40000 end_request: I/O error, dev sdb, sector .... Buffer I/O error on device dm-0, logical block... lost page write due to I/O error on device dm-0" keeps on popping up. Finally I got a message saying that "Remounting filesystem read-only" and can't access the disk any more. The problem is exactly like bug6262 in bugzilla, except for this happens when I set SATA mode to "compatibility"(not "AHCI"). I can confirm that it is fixed in the 2.6.18. But how to make SATA drive S3 work properly in 2.6.16.33? I found several similar bugs, but the final conclusion I got is "This is fixed in linux-2.6.18..." and I can not find the original patches against this problem. I think the patch set "ACPI support for SATA/PATA" from Forrest and updated by Kristen may be helpful. But I can't apply them to 2.6.16.33 due to too much changes in sata driver. Do I need to open a bug report in bugzilla? Does the patch set really make sense to my problem? If so, any patch I should apply first? If not, which patches I should test? Is there anyone who could show me what I should do please? Any comment is appreciated. Thanks in advance.
