Haiku CD Fails to Boot: "PANIC: I/O operation would need to be cut."

[tmmagee]

I tried to boot the Haiku CD on my former BeBox with the following results were:

1) Haiku splash screen appeared 2) Kernel panic occurred after the fourth icon on the splash screen lit up 3) The following message appeared on my screen:

"PANIC: I/O operation would need to be cut. Welcome to Kernel Debugging Land... Thread 30 "scsi scheduler" running on CPU 0 #debug>"

My machine is a Dell Dimension XPS T450. I looked up the specs on Dell's website and I have attached them to this ticket.

After kdebug> can you type in the command bt, use the command cont if needed.

[tmmagee]

cont didn't do anything for me, the kernel panic just kept reoccurring, but bt was a bit more informative. It told me that the panic appears to occur in <scsi_periph>. I don't have a digital camera with which I can take a picture of the screenshot unfortunately, but if you have any specific questions let me know.

[tmmagee]

Okay, it has been a while since I have looked at a kernel stack trace, but I think these are the important bits from the stack trace:

<kernel_x86> panic() ...
<scsi_periph> periph_io ...
<scsi_cd> do_io ...

So from what i am reading it appears that do_io (from scsi_cd) somehow calls periph_io and then periph_io panics.

Don't know if this helped. Again, let me know if you have any specific questions, and I apologize for the lack of camera.

I am also having this issue with a Panasonic CF-47 Toughbook laptop.

This was the snapshot dated 2010-01-10

Here's the debug info:

Also, if in case it may help identify hardware, here is an OpenBSD dmesg of the machine:

Seems this error occurs in file: src/add-ons/kernel/generic/scsi_periph/io.cpp

150 		if (numBlocks != originalNumBlocks)
151 			panic("I/O operation would need to be cut.");

On older CD-ROM drives, numBlocks value is changed under this if statement:

131 		// make sure we avoid 10 byte commands if they aren't supported
132 		if (!device->rw10_enabled || device->preferred_ccb_size == 6) {

This ticket is caused by changing numBlocks value in one of these, making it no longer equal to originalNumBlocks and triggering the panic:

135 			if (numBlocks > 0x100)
136 				numBlocks = 0x100;

Or

145 			if (pos < 0x100000)
146 				numBlocks = min_c(numBlocks, 0x100000 - pos);

I also have this problem. I think my Haiku liveCD is OK because it boots with no problems on a different laptop.

My hardware:

HP Omnibook XE2-DB notebook

Pentium II 333MHz CPU

256MB RAM

4.6GB Hard Drive

Teac 24X CD RO drive on ATAPI bus

800x600x24 LCD display

Silicon Motion SM811 LynxE video card

Hope the link to the pic of kernel debug screen is legible and helpful. You'll probably have to zoom to a higher magnification to read it.

Replying to tonestone57:

Either the panic shouldn't be there, or the comment near that code is wrong, IMHO. restricting transfer is OK - the block manager will take care of transferring the rest

if (numBlocks > 0x100)

numBlocks = 0x100;

But then originalNumBlocks is checked against numBlocks.

[scottmc]

I hope by BeBox you are referring to a PC that you had that you used to run BeOS on, and not a BeBox that was built by Be Inc in the 1990s, as Haiku won't work on those. ;)

Can you recheck this with a recent Haiku build?
