If HVM guest Fedora 7 uses PIT and lapic timer, it can''t boot or install. The cause is: At some point, Fedora 7 disables PIT interrupt by "vioapic.redirtbl[2].mask = 1, vpic.imr.bit0 = 0 (unmasked), vlapic.lvt[LINT0].mask = 1", and enables vlapic timer interrupt generating; In vmx_intr_assist() -> pt_update_irq(), we always choose IRQ0 rather than vlapic timer interrupt, because: 1) is_isa_irq_masked(v, 0) returns false due to vpic.imr.bit0 = 0; 2) the PIT''s pt->last_plt_gtime is less than...

Thomas, Have spoken to Soren, from my bootlog he believes that the problem is in atapicam causing the system to lock up. He is happy to answer some questions but doesnt have time to delve into atapicam himself. Did you author atapicam, I have seen your name on the sourcecode, can you help me further? Whats next? Thanks Adam. -------------- next part -------------- An embedded message was
