[ltp] T30 failes to resume from suspend

[Rune Froysa]

I'm having problems making my T30 (type 2366 - 92g) resume properly
from suspend.  The system wakes up, but when trying to access the hd,
the message "hda: lost interrupt" is printed and the process in
question hangs.  The powerswitch is needed to resume system
operation.  Sometimes I also get "ide_dmaproc: chipset supported
ide_dma_lostirq func only: 13", or "resume warning: bios doesn't
restore PCI state properly\nresume warning: if resume failed, try
booting with resume=force" (resume=force doesn't help).

About 1 of 5 resumes succeedes without problems.  On boot, the message
"IBM machine detected. Enabling interrupts during APM calls." is
printed (redhat 8.0, linux-2.4.18-18.8.0).  I've tried compiling
linux-2.4.20 with:

  CONFIG_APM_ALLOW_INTS=y
  # CONFIG_IDEPCI_SHARE_IRQ is not set
  CONFIG_IDEDISK_MULTI_MODE=y

as well as updating /etc/sysconfig/apmd with:

  HDPARM_AT_SUSPEND="-q -X0 -q -c0 -q -d0 -q -u0 -q -S10"
  HDPARM_AT_RESUME="-q -X66 -q -c1 -q -d1 -q -u1 -q -S30"

Are there any known solutions to this problem?
