Hello!
I have a problem with the libata and/or ata_piix drivers in linux kernel
2.6.x and 2.4.x versions.
The problem occured with the following hw combinations:
1. Maxtor 7Y250M0 250Gb sata disk
hp/compaq d530 cmt machine
// Vendor: ATA Model: Maxtor 7Y250M0 Rev: YAR5
// Intel Corp. 82801EB (ICH5) Serial ATA 150 Storage Controller (rev 02)
2. Maxtor 7Y250M0 250Gb sata disk
hp dc7110 machine
// Vendor: ATA Model: Maxtor 7Y250M0 Rev: YAR5
// IDE interface: Intel Corp. 82801FB/FW (ICH6/ICH6W) SATA Controller
(rev 03)
I can write only the first 308Mb on the disk.
Ex.:
Write ~1Gb zeros to disk
# dd if=/dev/zero of=/dev/sda bs=1024 count=1024000
1024000+0 records in
1024000+0 records out
1048576000 bytes transferred in 58.594727 seconds (17895399 bytes/sec)
Read 1024000 zeros from disk.
# dd if=/dev/sda bs=1024 count=1024000 |od -x |head
0000000 0000 0000 0000 0000 0000 0000 0000 0000

The logs and other tests are in the attachmet.
Please help if you can.
Best regards!
