I tried merging Linus's one-liner in front of alt4_v2, and the screen came back right away (instead of stalling 30seconds), and then the alt4_v2 code killed the interface as before. :) Jeff Garzik wrote:
Here's alt4 v3. Having the host_stat == 0x1 was suspicious. After digging through the hardware manual, it might be a good idea to configure BMDMA registers properly, in case that was done by BIOS but not by D3->D0 silicon reset values.
I'll try that. But does it make sense that Linus's one-liner would also work, if this was really the problem? (dunno, just asking)
One core problem with all of libata suspend/resume is that * we boot from a configuration set up by BIOS * but going D3->D0, we simply get silicon defaults Randy Dunlap's ACPI patches will probably help a bit.
The ACPI patches have indeed been working here for over a year now, on all kernels up to 2.6.15 --> not needed for 2.6.16. Cheers - : send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
