If you boot with "knoppix debug loglevel=9", you should see the logging
messages when booting. In the upcoming Knoppix 6 release, you see them
by switching to console 12.

I think the problem is this:
ata1: SATA max UDMA/133 abar m8192@0xfdefe000 port 0xfdefe100 irq 16
ata2: SATA max UDMA/133 abar m8192@0xfdefe000 port 0xfdefe180 irq 16
ata1: SATA link down (SStatus 0 SControl 300)
ata2: classification failed
ata2: reset failed (errno=-22), retrying in 8 secs
ata2: classification failed
ata2: reset failed (errno=-22), retrying in 10 secs
ata2: classification failed
ata2: reset failed (errno=-22), retrying in 35 secs
ata2: limiting SATA link speed to 1.5 Gbps
ata2: classfication failed, assuming ATA
ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 310)
Your SATA controller in in a inoperable state, and after a LOT of
timeouts and retries is being reset.
I'm not sure if there is a boot option to fix this. For IDE, ide0=reset
ide1=reset ide2=reset ide4=reset is known to work if an IDE DVD drive
refuses to work. But this is SATA in native mode, and I don't recall if
there is a similar kernel boot parameter. You may succeed when setting
SATA to "IDE compatible (Legacy) mode" in your computers BIOS, maybe
also booting with acpi=off can help.

Default is 104x768, however, the X servers randr extension may chose a
different resolution if it thinks it's supported.

Known bug in the framebuffer driver of older kernels. This goes away
when booting with the "vga=normal" option.
