Yes, if it doesn't bother you. Hmmm, it doesn't seem related with my SMP/i386 sleep patches. Could you try also Uni-processer kernel (w/o SMP and apic from config file) without my patches? > OTOH, IIRC the console only test (without X) without acpi_video lead to > freeze. No crash dump. The machine has no serial or fwire ports :( We can improve video initialization on another opportunity. Linux have many video hacks while we have only hw.acpi.reset_video ;) http://www.kernel.org/doc/Documentation/power/video.txt I believe there are some solutions for you in this document, then we can implement them in our source if found.
