Sorry for this taking too long. Finally I had the time to play with this again, so here goes the current summary. I have a system here, that: - with 1d67953f2bda8876045c24ae58841f27d9bb7572 (just before the setup code rewrite), resumes nicely in VGA console (acpi_sleep=s3_bios,s3_mode kernel parameter is needed), everything works - with c39736823232bc3ca113c8228fa852c09fba300e (just after the setup code rewrite), VGA text console is garbled after resume - looks like the video RAM contains some strange data (patterns from BIOS post can be recognized, there are some various-colored stripes across the screen, etc). The machine also seems to be frozen (no keyboard LEDs working, etc). - with 2.6.23-rc9, the video doesn't come up at all, I can't even see the garbled picture any more - the display stays blank, the LED diod is yellow (i.e. looks like completely no signal from VGA card). On the other hand, the machine seems to work otherwise -- Jiri Kosina - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
