SubjectIDE and APM (standby) incompatibility on thinkpad T21?
Attempting to 'standby' the machine generates the following
syslog messages:

Mar 27 23:58:56 localhost kernel: ide_dmaproc: chipset supported
ide_dma_lostirq func only: 13
Mar 27 23:58:56 localhost kernel: hda: lost interrupt

This seems to corrupt the filesystem..
