thanks for the response but I am still confused - I have a disk that requires 2.4.21-ac4 + libata5 (from Jeff Garzik), otherwise it does not recognize anything above 137GB (it recognizes disk as 250GB but all read/write attempts fail).
2.4.21 vanilla: freezes on boot 2.4.21-ac4 (SCSI_ATA): read/write above 1376GB fails 2.4.21-ac4 + libata5: works (libata changes manually merged in)
is this disk going to work without libata patch?
MB: intel D865PERL Maxtor 250GB SATA disk
here's what kernel thinks about the disk (from dmesg):
subsystem driver Revision: 1.00 ata_piix version 0.93 PCI: Setting latency timer of device 00:1f.2 to 64 ata1: SATA max UDMA/133 cmd 0xEC00 ctl 0xE802 bmdma 0xDC00 irq 18 ata2: SATA max UDMA/133 cmd 0xE400 ctl 0xE002 bmdma 0xDC08 irq 18 ata1: dev 0 cfg 49:2f00 82:7c6b 83:7f09 84:4003 85:7c69 86:3e01 87:4003 88:207f ata1: dev 0 ATA, max UDMA/133, 490234752 sectors (lba48) ata1: dev 0 configured for UDMA/133 ata2: thread exiting scsi0 : ata_piix scsi1 : ata_piix Vendor: ATA Model: Maxtor 6Y250M0 Rev: 0.70 Type: Direct-Access ANSI SCSI revision: 05 libata version 0.70 loaded.
