AHCI: Error while READ LOG EXT

[Julien Cigar]

Hello,

I got strange errors from ahci this morning (on a 8.2-RELEASE box):

+ahcich3: Error while READ LOG EXT
+ahcich3: Error while READ LOG EXT
+GEOM_MIRROR: Request failed (error=5). ada1[READ(offset=457644130304, 
length=16384)]
+GEOM_MIRROR: Device backup: provider ada1 disconnected.
+(ada1:ahcich3:0:0:0): Synchronize cache failed
+ahcich3: Error while READ LOG EXT
+ahcich3: Error while READ LOG EXT
+ahcich3: Error while READ LOG EXT

The disks are quite recent, so I wondered if it could be a bug in the 
ahci driver .. ?

The controller is a JMicron:

ahci1 at pci0:0:31:2:      class=0x010601 card=0x81ec1043 chip=0x28248086 
rev=0x02 hdr=0x00
     vendor     = 'Intel Corporation'
     device     = '82801HR/HO/HH (ICH8R/DO/DH) SATA AHCI Controller'
     class      = mass storage
     subclass   = SATA

ahci0 at pci0:2:0:0:       class=0x010601 card=0x81e41043 chip=0x2363197b 
rev=0x03 hdr=0x00
     vendor     = 'JMicron Technology Corp.'
     device     = 'JMicron JMB362/JMB363 AHCI Controller (JMB36X)'
     class      = mass storage
     subclass   = SATA

atapci0 at pci0:2:0:1:     class=0x010185 card=0x81e41043 chip=0x2363197b 
rev=0x03 hdr=0x00
     vendor     = 'JMicron Technology Corp.'
     device     = 'JMicron JMB362/JMB363 AHCI Controller (JMB36X)'
     class      = mass storage
     subclass   = ATA


thank you,
Julien
