scsi : aborting command due to timeout, commands queued exceeds queue depth, active=255

[Robert Sander]

Hi!

I have a SMP-System and had the same problems since 5.1.0, but now with
5.1.2 this does not happen until now (36h uptime, knock on wood...).

This is my /proc/scsi/scsi:

Attached devices: 
Host: scsi0 Channel: 00 Id: 06 Lun: 00
  Vendor: IBM      Model: DCAS-34330W      Rev: S65A
  Type:   Direct-Access                    ANSI SCSI revision: 02

And this is my /proc/scsi/aic7xxx/0:

Adaptec AIC7xxx driver version: 5.1.2/3.2.4
Compile Options:
  AIC7XXX_RESET_DELAY    : 15
  AIC7XXX_TAGGED_QUEUEING: Adapter Support Enabled
                             Check below to see which
                             devices use tagged queueing
  AIC7XXX_PAGE_ENABLE    : Enabled (This is no longer an option)
  AIC7XXX_PROC_STATS     : Enabled
