| |
Hi,
I just got an external e-SATA hard disk, and I'm testing for backup.
When I tried to "tar" 90GB to it, it caused a HSM violation, and since this is the root file system, system is brain-dead. "Bus error" for every command issued!
Error is (typed as was captured in the screen) ...
ata1.00: exception Emask 0x2 SAct 0x7 SErr 0x3000400 action 0x6 ata1.00: irq_stat 0x44000008 ata1.00: cmd 60/30:00:37:b0:84/00:00:17:00:00/40 tag 0 ncq 24576 in res 40/00:08:6f:b0:84/00:00:17:00:00/40 Emask 0x2 (HSM violation) ata1.00: cmd 60/50:08:6f:b0:84/00:00:17:00:00/40 tag 1 ncq 40960 in res 51/04:00:6f:b0:84/00:00:17:00:00/40 Emask 0x403 (HSM violation) ata1.00: cmd 60/00:10:bf:b0:84/01:00:17:00:00/40 tag 2 ncq 131072 in res 40/00:08:6f:b0:84/00:00:17:00:00/40 Emask 0x2 (HSM violation) ata1: hard resetting link ata1: softreset failed (device not ready) ata1: hard resetting link ata1: softreset failed (device not ready) ata1: hard resetting link ata1: link is slow to respond, please be patient (ready=0)
Running on SSD on Linux 2.6.35-rc3.
This does not happen all the time, but I've seen this if it's copying intensively.
Thanks, Jeff.
