[ltp] Lost Interrupt on TP 600X

[linux-thinkpad@www.bm-soft.com]

Best guess is this, when using the Adaptec card by default it wants to use
IRQ 15 (cdrom/secondary controller) which is already in use.  Because of
machine configuration (even unused items such as serial/parrallel ports,
etc.) there are probably no IRQ's available for the Adaptec card to use.
I've also noticed that the driver being used is for generic ide (not PIIX4
driver) when linux loads.  It might get lost here.

Subject:  [ltp] Lost Interrupt on TP 600X




I have been encountering the error,

     hda: lost interrupt

while attempting to back-up and/or restore the hard disk
on my TP 600X (Red Hat 6.1, kernel 2.2.12).  I am using an
HP DAT drive with an Adaptec 1460 PCMCIA SCSI card.  The error
appears when using tar or dump.  I have tried using two different
hard disks, a 6 gb Travelstar and a 12 gb Travelstar, and the
error has appeared with both.  It appears at different times
during the backup or restore, but, once it appears, it's fatal
and the system can be brought back only by restarting with the
power switch.

I would appreciate any information or speculation as to what
might be the problem.

Thanks.
