Re: SCSI related hang on boot

[Kai OM]

I did some digging around, and found a patch issued in 2.6.6 - here's the
entry in the changelog:

<willy@xxxxxxxxxx>
	[PATCH] sym 2.1.18j
	
	sym 2.1.18j:
	 - Add SPI transport attributes (James Bottomley)
	 - Use generic code to do Domain Validation (James Bottomley)
	 - Stop using scsi_to_pci_dma_dir() (Christoph Hellwig)
	 - Change some constants to their symbolic names (Grant Grundler)
	 - Handle a race between a postponed command completing and the EH retrying
	   it (James Bottomley)
	 - If the auto request sense fails, issue a device reset (James Bottomley)

It looks like this patch broke something, though I have no clue what,
because ALL tested previous versions of the Sym driver have worked for
me.

I tested 2.6.6-r1 a little bit with noapic and nolapic, and it didn't
help, but I can see if 2.6.6 is any different. Either way, that's just a
workaround, and doesn't address whatever was broken in the actual code.

So far, I've tested this in Slackware and Gentoo, though I can't imagine
how the distro you use would affect the boot process before the root FS
is even mounted. I'm not terribly informed, though, so

Subject: Re: SCSI related hang on boot

I've seen something similar on my intel 440bx with a dual integrated 
sym53c875.  With some distro kernels booting with noapic helps.  In 
other cases I have to be sure the use the older symbios module.
