Partition information lost on reboot.

Partition information lost on reboot.

[Jegadeesh]

Hi,

I have a scsi disk on Adaptec ASC-29320 U320. I have created a linux
partition and ext3 filesystem over it.
Now the problem is, whenever the machine is rebooted, the partition
information to the OS is lost and I get an error saying it as a not valid
block device.
But fdisk tool shows the partitions, but "cat /proc/partitions" doesnt have
this. I need to do a "partprobe" and then have to mount it explicitly.

What could be causing this problem. Given below are some of the command
outputs.

# uname -a
Linux pr.vionline.net 2.6.18-1.2798.fc6 #1 SMP Mon Oct 16 14:37:32 EDT 2006
i686 i686 i386 GNU/Linux

# mount /dev/sda1 /disk1
mount: /dev/sda1 is not a valid block device

# fdisk -l /dev/sda

Disk /dev/sda: 73.4 GB, 73407900160 bytes
255 heads, 63 sectors/track, 8924 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Is that the "Adaptec AIC79xx U320 support" (CONFIG_SCSI_AIC79XX) driver? If 
so, did you lower the "Initial bus reset delay" (default is 5000 ms) in the 
kernel configuration?
