ata_hpt37x and the case of the missing partition...

Hi all, I have just tried out the new libata drivers and have some weirdness going on with my Highpoint 370a based PCI IDE controller.
Here is the situation.
3 drives on onboard controller.
4 drives on Highpoint PCI controller.

Old IDE driver: Card detected as a 366, configured for udma 66. I KNOW this card has a 370A chipset. but all works well.
New PATA driver: Card detected as a 370, configured for udma 100. But the partition on the secondary master drive (sde1) doesn't show up in /dev or /proc/partitions.
cfdisk can see it and dmesg shows 'sde: sde1' so I assume the driver can see it too.
If I re-write the partition table with fdisk it spontaneously shows up in /dev and /proc/partitions and can be accessed normally, but after a reboot it is gone again.

Does this sound like a hardware or software issue?

cat /proc/partitions:

   8     0   78150744 sda
   8     1      40131 sda1
   8     2     996030 sda2

Edit: This appears to be an intermittent issue, as all drives came up fine yesterday, but back to the missing partition trick today.

Edit: Removing and reloading the pata_hpt37x module seems to do the trick also.

Any ideas on how I can narrow this down?

Why would the driver say "sde: sde1" and not show it in /proc/partitions?

Cheers,

Steve.

Re: ata_hpt37x and the case of the missing partition...

Tried that today.

However putting pata_hpt37x in the MODULES array in mkinitcpio _seems_ to fix the issue, 3 boots in a row with all partitions recognised.
Something to do with driver loading order?

Cheers,

Steve.
