Hello Gwendal, Thank you for your information. I think ata8 might different from other 3 PMPs. I'll try to update all firmware but it is running resync on broken RAID now. So I can't do it soon. By the way, both of ata8 and ata9 loses some HDDs also. Are those affected by PMPs on ata7 and ata10? Why 3.1.x driver can work? Best Regards, Akira > Now I see your problem. Indeed on ata7, ata10, we have a problem. > I notice however some messages I did not see before: >>> [ 4.856382] ata7.15: Port Multiplier 1.1, 0x1095:0x3726 r23, 6 ports, feat 0x1/0x9 >>> [ 4.858742] ata7.00: hard resetting link >>> [ 14.843039] ata7.00: softreset failed (timeout) >>> [ 17.836402] ata7.15: qc timeout (cmd 0xe4) > The later indicates that the PMP is stuck and the host can not read > its internal register. > Is it possible that the PMP in these 4 enclosures you are using have a > different firmware than the other ones? > Firmware 1.0114 is available at: > http://www.siliconimage.com/support/searchresults.aspx?pid=26&cat=23 > > From the release notes: > """- Fix SRST and initial two RegFIS Problem.""" > > Gwendal. -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
