Has anyone else experienced a problem using Adaptec
2940U2 controllers where the scsi bus will continuously
reset and cause the system to lock up. This has been
happening to be, especially on boot up. I have to reset
my system on average 5 to 10 times before I'm able to
fully boot to the desktop, at which point, it normally
runs stable.
 
Try going to run,type:Msinfo32
Chk in hardware,conflicts.You might also open event viewer
for detailed info on the system.
 
I have MPS1.4/APIC enabled on my system doubling my IRQs and made sure the scsi controller was in a slot not sharing with any other device. There are no hardware conflicts.

IRQ 0 System timer OK
IRQ 1 Standard 101/102-Key or Microsoft Natural PS/2 Keyboard OK
IRQ 3 Communications Port (COM2) OK
IRQ 4 Communications Port (COM1) OK
IRQ 6 Standard floppy disk controller OK
IRQ 7 ECP Printer Port (LPT1) OK
IRQ 8 System CMOS/real time clock OK
IRQ 9 Microsoft ACPI-Compliant System OK
IRQ 12 Logitech-compatible Mouse PS/2 OK
IRQ 13 Numeric data processor OK
IRQ 14 Primary IDE Channel OK
IRQ 15 Secondary IDE Channel OK
IRQ 16 RADEON 9100 SERIES OK
IRQ 16 HighPoint HPT3xx ATA RAID Controller OK
IRQ 17 Realtek RTL8139/810x Family Fast Ethernet NIC OK
IRQ 17 RADEON 9100 SERIES OK
IRQ 17 Intel(r) 82801BA/BAM AC'97 Audio Controller OK
IRQ 18 Adaptec AHA-2940U2 - Ultra2 SCSI OK
IRQ 19 Texas Instruments OHCI Compliant IEEE 1394 Host Controller OK
IRQ 19 Intel(r) 82801BA/BAM USB Universal Host Controller - 2442 OK
IRQ 23 Intel(r) 82801BA/BAM USB Universal Host Controller - 2444 OK

The controller is manufactured by Micron PC, and it is using the latest firmware available through them. I have also tried reflashing it with adaptec's U2W firmware, in which case the controller still worked (but it's bios couldn't find a suitable adapter if you tried to enter setup - but thats not important), and it still experienced these lockups. If I have my plextor 12/20plex cdrom connected, I can tell when the problem occurs because the access light will continuely flash, the same way it does when it first powers up. Additionally, my boot hard drive, which is on the same singled ended channel will have long flashes on the access light. The drives on the LVD channel do not show any sign of access however.
 
Eric,
What version ASPI driver are you using? May I suggest you roll back and use
version 4.70. The driver is still offered on the Adaptec web site (do a
search on the site). If you have aspichk.exe installed on your system, using
it will reveal what version ASPI driver you are using (can also be found at
Adaptec web site). The latest ASPI drivers(4.71a2 & 4.71) have problems with
older host adapters on WinXP platforms. The older version 4.70 (Feb 2002)
seems to work best.

If you have problems locating these drivers I can e-mail them to you....

Good Luck

Seeing as how windows itself does not rely on ASPI, and
this problem is not regularly occuring when ASPI would be
used (but rather mainly in the first few minutes of
operation, especially at boot up), I dont think this
would be the problem. However, to answer your question I
have version 4.60 (1021) installed.
