root@muur:/var/www/htdocs# hdparm -i /dev/hda
/dev/hda:
Model=QUANTUM FIREBALLP AS20.5, FwRev=A2R.0600, SerialNo=692124031358 Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs } RawCHS=16383/16/63, TrkSize=32256, SectSize=21298, ECCbytes=4 BuffType=DualPortCache, BuffSize=1902kB, MaxMultSect=16, MultSect=16 CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=40132503 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 *udma5 AdvancedPM=no WriteCache=enabled Drive conforms to: ATA/ATAPI-5 T13 1321D revision 1:

On the other hand: root@muur:/var/www/htdocs# hdparm -d /dev/hda
/dev/hda: using_dma = 0 (off)
That is puzzling me as I explicitly swith that on in the startupscripts: 0 root@muur:/var/www/htdocs# grep hdparm /etc/rc.d/* /etc/rc.d/rc.local:/usr/sbin/hdparm -c 3 -d 1 -X 69 -u 1 /dev/hda &
So it seems it switches back to pio somewhere in time.
But on the other hand: shouldn't pio run ok as well without softlockup errors?
