Hi,

dapper and edgy installed flawlessly with "pci=noapic" on my Thinkpad R30. acpi=off is NOT needed, but PCI/IRQ-Routing should be set to "Automatic" in the BIOS. Even suspend to disk works. The only remaining problem is suspend to ram (which did not bother me much). There are ACPI-related errors in the dmesg output. My attempts at fixing the DSDT only removed some errors with the laptop working (or not re s2ram) as before, so I dumped my handrolled DSDT.

After having upgraded to feisty, booting & running still works with pci=noapic, but resume after suspend to disk fails. Last output is the completion of loading the memory dump from swap space, after that the screen blanks (backlight goes out) and the laptoip hangs until switched off. A little debugging shows that all suspend scripts (/etc/acpi-support/suspend.d/*) are being run, but none of the resume scripts (/etc/acpi/resume.d). Booting the 2.6.17-11 kernel of edgy restores suspend to disk functionality, so it's probably a kernel related problem and not a dying X server.

I'll gladly post more information if needed.

Cheers,
