Re: Promise IDE controller crashes 2.4.22

["Andrew Herdman" <andrew@whine.com>]

to determine the UDMA mode the drive is currently operating in perform a
hdparm -i /dev/hde

an example from my system, Promise TX133 Card

hdparm -i /dev/hde

/dev/hde:

 Model=WDC WD800JB-00DUA3, FwRev=75.13B75, SerialNo=WD-WMACM1696962
 Config={ HardSect NotMFM HdSw>15uSec SpinMotCtl Fixed DTR>5Mbs FmtGapReq }
 RawCHS=16383/16/63, TrkSize=57600, SectSize=600, ECCbytes=74
 BuffType=DualPortCache, BuffSize=8192kB, MaxMultSect=16, MultSect=16
 CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=156301488
 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}
 PIO modes:  pio0 pio1 pio2 pio3 pio4
 DMA modes:  mdma0 mdma1 mdma2
 UDMA modes: udma0 udma1 udma2 udma3 *udma4
 AdvancedPM=no WriteCache=enabled
 Drive conforms to: device does not report version:

 * signifies the current active mode

As you can see, my drive is currently operating using udam4 (i turned off
udma5 on the drives themselves because of dma errors, bad cabling).
