March 8, 201313 yr I just finished upgrading my power supply and adding a new disk. The new power supply is a 650 Watt that can supply 54A on a single 12V rail (+3.3V@24A,+5V@22A,+12V@54A,[email protected],+5VSB@3A). While running preclear on the new disk, I noticed the following errors if I spinup several (4 or more) other drives at once: Mar 8 08:06:27 Tower kernel: ata14.00: exception Emask 0x0 SAct 0x7fffffff SErr 0x0 action 0x6 frozen (Errors) Mar 8 08:06:27 Tower kernel: ata14.00: failed command: WRITE FPDMA QUEUED (Minor Issues) Mar 8 08:06:27 Tower kernel: ata14.00: cmd 61/00:00:f8:59:f6/04:00:93:00:00/40 tag 0 ncq 524288 out (Drive related) Mar 8 08:06:27 Tower kernel: res 40/00:84:f8:01:f1/00:00:93:00:00/40 Emask 0x4 (timeout) (Errors) Mar 8 08:06:27 Tower kernel: ata14.00: status: { DRDY } (Drive related) The errors repeat 30 times (up to tag 30 in the ncq), the sata link is reset and things continue without a problem. Would this possibly be caused by insufficient power for the drives to spinup and continue IO to the drive? I would have thought that the power supply could handle the load, but could be wrong. Any other thoughts? Thanks in advance. syslog-2013-03-08.txt
