suspend to ram regression in current GIT, bisected
Hi,
starting from 2.6.27-rc1, my Laptop (Thinkpad T60) did not return from
suspend to ram anymore.
When it should resume, the sleep LED went off, power went on, HD LED
flashed once, but the display stayed black.
It worked perfectly in 2.6.26, so I bisected it:
ce6fce4295ba727b36fdc73040e444bd1aae64cd is first bad commit
commit ce6fce4295ba727b36fdc73040e444bd1aae64cd

PCI MSI: Don't disable MSIs if the mask bit isn't supported
David Vrabel has a device which generates an interrupt storm on the INTx
pin if we disable MSI interrupts altogether. Masking interrupts is only
a performance optimisation, so we can ignore the request to mask the
interrupt.

Reverting it was not a problem and fixed the issue.
As the screen stays black, I have no idea how to get further details on
that problem. Which additional information should I provide? Netconsole
didn't show anything.

Yes the patch fixed it here. It also fixes IO garbage while shutting
down here.
Thanks!
