(HPT372A) cat /proc/ide/hpt366 == crash

["Gavin Baker" <gavbaker@linuxmail.org>]

I have an Highpoint "RocketRaid 133" dual channel PCI IDE "raid" controller that uses an HPT372A.

With the latest 2.4's and 2.6.0-test9, if I cat /proc/ide/hpt366 I get the ide channel status followed shortly after by:

  hdg: status timeout: status=0xd0 {Busy}
                                                                                               
  hdg: DMA disabled 
  hdg: drive not ready for command
  ide3: reset: master: error (0x00?)
  hdg: status timeout: status=0xd0 {Busy}
                                                                                               
  hdg: drive not ready for command
  ide3: reset: master: error (0x00?)
  end-request: I/O error, dev hdg, sector xxxxxx
  EXT3-fs error (device md0): ext3_get_inode_loc: unable to read inode
  block - inode = xxxxxx, block = xxxxxx

With the last two lines repeating until there is total filesystem corruption.

In regular usage they have been fine (I've built my distro from source without a problem).

Both drives are new seagate barracudas. They both have DMA enabled. I use regular kernel raid0, not the software raid drivers.

Probably related, the SMART data from these drives is showing Hardware_ECC_Recovered is up over 31 and 120 million, with Power_On_Hours less than 250.

Any ideas?

Thanks,
Gavin Baker
