[ale] Possible errors on Hard Drive

[Scott Castaline]

Checking my logs and noticed that I'm suddenly getting what looks like 
drive errors but not sure. I've noticed the following repeated about 3 
times every once in a while:
ata4.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2
ata4.00: port_status 0x20080000
ata4.00: cmd c8/00:30:ef:e8:cb/00:00:00:00:00/e6 tag 0 cdb 0x0 data 24576 in
         res 50/00:00:1e:e9:cb/00:00:00:00:00/e6 Emask 0x2 (HSM violation)
ata4: soft resetting port
ata4: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
ata4.00: configured for UDMA/133
ata4: EH complete

followed by:
sd 3:0:0:0: [sdd] 976773168 512-byte hardware sectors (500108 MB)
sd 3:0:0:0: [sdd] Write Protect is off
sd 3:0:0:0: [sdd] Write cache: enabled, read cache: enabled, doesn't 
support DPO or FUA

I just recently changed HA from an Adaptec 2 port SATA 150 to a Promise 
SATA 300TX4, 4 port SATA 300. I have all WD drives.
port 1 = WD1600  (150)
port 2 = WD5000  (300)
port 3 = WD360    (150)  Raptor 10K rpm
port 4 = WD360    (150)  Raptor 10K rpm

Any ideas? Everything I've found is close, but no cigar. Also any 
documentation I've found is like from 2004. I'm not too sure how current 
that is.
