Some SATA harddrives will not load with newer libata drivers. The following is a short description of the bug from the vanilla kernel developers: "WDC WD1600JS-62MHB5 successfully hits the window between ATA/ATAPI-7 and Serial ATA II standards and reports 3c/c3 signature which now is assigned to SEMB. Make ata_dev_classify() report ATA_DEV_SEMB on the sig and let ata_dev_read_id() work around it by trying IDENTIFY once." Reproducible: Always Steps to Reproduce: 1. Try to install gentoo with gentoo-sources with WDC WD1600JS-62MHB5 hard drive 2. 3. Actual Results: /dev/sdb is no where to be found! Expected Results: Loaded /dev/sdb The problem has been addressed and fixed/'worked around' for the vanilla kernel and is being addressed for the ubuntu kernel. This affects gentoo as well as several other distributions that I have tried with a 2.6.4 or newer kernel. I have applied the vanilla kernel patch to gentoo-sources 2.6.27 and then successfully been able to load my western digital WDC WD1600JS-62MHB5 hard drive. Here is the vanilla bug report and patch : http://bugzilla.kernel.org/show_bug.cgi?id=11579 Patch: http://bugzilla.kernel.org/attachment.cgi?id=20986 Ubuntu bug report: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/257790
Can I expect a gentoo distribution fix?
Correction: This affects gentoo as well as several other distributions that I have tried with a 2.6.24 or newer kernel
