Greets.
I am experiencing lockups (no log messages) on a Linux system, running
2.0.33, using either the stock 2.0.33 driver or the new 5.0.7 driver using
an Adaptec 2940W and an IBM DCHS04U wide internal drive.
/proc/pci reports:
Bus 0, device 12, function 0:
SCSI storage controller: Adaptec AIC-7871 (rev 0).
Medium devsel. Fast back-to-back capable. IRQ 10. Master Capable.
/proc/scsi/scsi:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: IBM OEM Model: DCHS04U Rev: 5353
Type: Direct-Access ANSI SCSI revision: 02
/proc/scsi/aic7xxx/0 (driver version 5.0.7):
Adaptec AIC7xxx driver version: 5.0.7/3.2.2
Compile Options:
AIC7XXX_RESET_DELAY : 15
AIC7XXX_TAGGED_QUEUEING: Adapter Wide Support Enabled.
AIC7XXX_PAGE_ENABLE : Enabled (This is no longer an option)
AIC7XXX_PROC_STATS : Disabled
Adapter Configuration:
SCSI Adapter: Adaptec AHA-294X SCSI host adapter
Wide Controller
Base IO: 0xe400
Base IO Memory: 0xfbbff000
BIOS Memory Address: 0x0
Enabled
IRQ: 10
SCBs: Active 0, Max Active 1,
Allocated 30, HW 16, Page 255
Interrupts: 4843
BIOS Control Word: 0x0096
Adapter Control Word: 0x005c
Extended Translation: Enabled
SCSI Bus Reset: Enabled
Disconnect Enable Flags: 0xffff
Tag Queue Enable Flags: 0x0000
Ordered Queue Tag Flags: 0x0000
Tagged Queue By Device array for aic7xxx host instance 0:
{255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255}
Actual queue depth per device for aic7xxx host instance 0:
{1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1}
The system locks, with the drive access light on, whenever I do extended
writes, normally within a few minutes of starting the operation. No errors
are logged out to any of the logfiles or printed on the screen.
Oddly enough, the system seemed to work fine under a slackware
installation that was recently replaced with redhat 5.0.
It is a single drive on the internal bus, with a high-quality, short cable
and active termination on the drive. The interface on the card is
terminated as well.
Does anyone have any ideas what might be causing this? Would upgrading the
card bios help? Currently it is at version 1.11.
Thanks in advance,
