Unfortunately this is not an artifact of the linux raid driver, rather it appears to be an issue with the SATA driver and related error recovery. Some information about what kernel, configuration, drives, controller cards and other relevant system information would be good. See the information at this URL for the sort of extra information that would be handy. http://www.kernel.org/pub/linux/docs/lkml/reporting-bugs.html Regards, Brad -- "Human beings, who are almost unique in having the ability to learn from the experience of others, are also remarkable for their apparent disinclination to do so." -- Douglas Adams
Ok no problem. I have a DELL SC1425 with a no card controler, only chipset for SATA and FakeRAID (Intel Chipset and Adaptec for FakeRAID but i have disable this function) : 00:1f.1 IDE interface: Intel Corporation 82801EB/ER (ICH5/ICH5R) IDE Controller (rev 02) 00:1f.2 IDE interface: Intel Corporation 82801EB (ICH5) SATA Controller (rev 02) Specs of the server here : http://www.dell.com/downloads/global/products/pedge/en/sc1425_specs.pdf Hard Drivers are 2 S-ATA Model=WDC WD800JD-75LSA0. I use , in my kernel configuration 2.6.21.5 : - "ATA device support" (CONFIG_ATA) -- "Intel ESB, ICH, PIIX3, PIIX4 PATA/SATA support" Driver (CONFIG_ATA_PIIX) And get this messages during my boot : [ 30.961007] libata version 2.20 loaded.
