Ok, here is the latest
Dropped to 13.4 - Still get the timeouts
Dropped to 10 (lowest) - get this error again (same error when disabled
disconnects)
<4> scsi0: (-1:-1:-1) Referenced SCB 255 not valid during SELTO
<4> SCSISEQ=0x5a SEQADDR=0x7 SSTAT0=0x10 SSTAT1=0x88
<6> scsi0: (-1:-1:-1) Invalid WAITING_SCBH value 128, improvising
I want to run something by you guys. When I first boot up, I get
<4>scsi : 0 hosts.
<4>scsi : detected total.
initially (right before the partition check), and only when it installs the
modules does it recognize the card.
Is this normal?
Any other ideas?
Can someone tell me what the driver is even doing in that initial probe?
