French newbie question :
I have installed redhat 5.1 on a quantum viking II scsi hard drive using
an adaptec 2940UW controller. Everything worked perfectly. There was the
default configuration from /proc/scsi/aic7xxx/0 :
Adaptec AIC7xxx driver version: 5.0.13/3.2.4
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 : Disabled
Adapter Configuration:
SCSI Adapter: Adaptec AHA-294X Ultra SCSI host adapter
Ultra Wide Controller
PCI MMAPed I/O Base: 0xe1000000
Adaptec SCSI BIOS: Enabled
IRQ: 10
SCBs: Active 0, Max Active 1,
Allocated 30, HW 16, Page 255
Interrupts: 2346
BIOS Control Word: 0x18a6
Adapter Control Word: 0x005e
Extended Translation: Enabled
SCSI Bus Reset: Enabled
Disconnect Enable Flags: 0xffff
Ultra Enable Flags: 0xffff
Tag Queue Enable Flags: 0x0000
Ordered Queue Tag Flags: 0x0000
Default Tag Queue Depth: 8
Tagged Queue By Device array for aic7xxx host instance 1:
{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 1:
{1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1}
Then I had the stupid idea to upgrade the kernel from 2.0.34-0.6 to
2.0.36-0.7. Apparently, all went OK, but when I had my system reboot,
and tried to copy a big file, the system lockedup for a few seconds,
then continued copying, then locked again, then.... until the copy was
done. A few things have changed in my scsi config as you can see :
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
Adapter Configuration:
SCSI Adapter: Adaptec AHA-294X Ultra SCSI host adapter
Ultra Wide Controller
PCI MMAPed I/O Base: 0xe1000000
Adapter SEEPROM Config: SEEPROM found and used.
Adaptec SCSI BIOS: Enabled
IRQ: 10
SCBs: Active 0, Max Active 1,

Extended Translation: Enabled
Disconnect Enable Flags: 0xffff
Ultra Enable Flags: 0x0001
Tag Queue Enable Flags: 0x0000
Ordered Queue Tag Flags: 0x0000
Default Tag Queue Depth: 8
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}
but I don't understand a word of it, and don't know neither how to
change this config without reinstalling everything.
Can someone help me ?
