about the same boot problem for me on ASUS A50VM. Sometimes the system boot normally.
Sometimes it beep and display boot text until the log screen, and then start normally. Sometimes the beeps don't stop after log screen. In the worst cases, the system hang up and display black screen (?? num lock led flashing). No way to get out of that except turning off. Here is the result on a dmesg command for a normal boot [ 0.593206] pci 0000:00:1e.0: MEM window: 0xfeb00000-0xfebfffff [ 0.593210] pci 0000:00:1e.0: PREFETCH window: disabled [ 0.593224] pci 0000:00:01.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 [ 0.593228] pci 0000:00:01.0: setting latency timer to 64 [ 0.593234] pci 0000:00:1c.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 [ 0.593239] pci 0000:00:1c.0: setting latency timer to 64 [ 0.593247] pci 0000:00:1c.1: PCI INT B -> GSI 17 (level, low) -> IRQ 17 [ 0.593252] pci 0000:00:1c.1: setting latency timer to 64 [ 0.593260] pci 0000:00:1c.2: PCI INT C -> GSI 18 (level, low) -> IRQ 18 [ 0.593265] pci 0000:00:1c.2: setting latency timer to 64 [ 0.593273] pci 0000:00:1c.3: PCI INT D -> GSI 19 (level, low) -> IRQ 19 [ 0.593277] pci 0000:00:1c.3: setting latency timer to 64 [ 0.593285] pci 0000:00:1c.4: PCI INT A -> GSI 16 (level, low) -> IRQ 16 [ 0.593289] pci 0000:00:1c.4: setting latency timer to 64 [ 0.593297] pci 0000:00:1c.5: PCI INT B -> GSI 17 (level, low) -> IRQ 17 [ 0.593301] pci 0000:00:1c.5: setting latency timer to 64 [ 0.593309] pci 0000:00:1e.0: setting latency timer to 64 a boot with beep and text ending on a normal log screen [ 1.010241] pci 0000:00:1c.5: MEM window: 0xfea00000-0xfeafffff [ 1.010250] pci 0000:00:1c.5: PREFETCH window: 0x000000f8f00000-0x000000f8ffffff [ 1.010264] pci 0000:00:1e.0: PCI bridge, secondary bus 0000:09 [ 1.010269] pci 0000:00:1e.0: IO window: disabled [ 1.010279] pci 0000:00:1e.0: MEM window: 0xfeb00000-0xfebfffff [ 1.010288] pci 0000:00:1e.0: PREFETCH window: disabled [ 1.010315] pci 0000:00:01.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 [ 1.010325] pci 0000:00:01.0: setting latency timer to 64 [ 1.010339] pci 0000:00:1c.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 [ 1.010349] pci 0000:00:1c.0: setting latency timer to 64 [ 1.010367] pci 0000:00:1c.1: PCI INT B -> GSI 17 (level, low) -> IRQ 17 [ 1.010377] pci 0000:00:1c.1: setting latency timer to 64 [ 1.010394] pci 0000:00:1c.2: PCI INT C -> GSI 18 (level, low) -> IRQ 18 [ 1.010404] pci 0000:00:1c.2: setting latency timer to 64 [ 1.010420] pci 0000:00:1c.3: PCI INT D -> GSI 19 (level, low) -> IRQ 19 [ 1.010430] pci 0000:00:1c.3: setting latency timer to 64 [ 1.010445] pci 0000:00:1c.4: PCI INT A -> GSI 16 (level, low) -> IRQ 16 [ 1.010455] pci 0000:00:1c.4: setting latency timer to 64 [ 1.010470] pci 0000:00:1c.5: PCI INT B -> GSI 17 (level, low) -> IRQ 17 [ 1.010480] pci 0000:00:1c.5: setting latency timer to 64 [ 1.010494] pci 0000:00:1e.0: setting latency timer to 64 As you can see, there are some differences of timing and in the first messages.
