It's Ctrl+Alt+F2 and Ctrl+Alt+F7 to return.
I understand completely. Because it's a SCSI controller you need the driver
so that you can install it into your SCSI-discs.

These loops may be optimized out of existence. Declare
a volatile int and do an operation on it in the inner
loop:
volatile int volatile_counter;
void really_do_nothing (void * n)
{
for (unsigned long i = *(unsigned long*)n; i > 0; i--)
for (unsigned long j = *(unsigned long*)n; j > 0; j--)
volatile_counter++;
}

What tools exist to debug linux kernel code, other than liberal
printk's? Is there a version of adb or crash for linux? I would prefer
to have something that doesn't cause me to rebuild the kernel (I'm just
building and installing my own device driver and kernel module), but
will consider anything!

real gurus use newsreaders which can *score* as opposed to just
killing. you assign a score to each post, sort based on the scoring
and kill-off scores which are below some threshold. this makes usenet
better for me. slrn and gnus use scoring. maybe others do too.
i score on a lot of things. some suggestions for low score
* subject consisting of the word "test".
* three dollar signs in subject ($$$) since make money fast sucks.
* kill anything cross-posted to two or more advocacy groups and avoid
those pointless flame fests.
* incrementally lower score based on number of cross posts and
exclaimation marks. (crossing to a few groups or one bang is ok. a
dozen crossposts and bangs usually indicates drivel.)
* postings whos subject end in a space followed by a four
digit number (these tend to be produced by spam software).
* very long posting in non-binary group.
* kill a particular thread in a particular newsgroup. this is based
on subject, but very specific.
boosting the score is also useful
* responses to my own posts
* posts made by people i have identified as clueful (kind of an
anti-kill)

I have a problem when it boots...
I noticed that the structure of the /lib/modules/ 2.4.0-test6 is changed from
the way it was in eariler kernels.
I suspect "make modules_install" is screwed up...

In my drivers I have:
#define MODULE
#define __KERNEL__
Before the includes of course.

You could try a platform that actually implements posix threads. (See
the recent thread on shared pids). The problem is that time uses wait3
to get its numbers, but every "thread" in LinuxThreads is a process,
so you only get accounting information from the first one.

The numbers are an attempt to trick sites which drop duplicate
postings into accepting unlimited copies of the same spam. You'll also
see trailing garbage in some spam, to avoid checks based on the body
content.

Up to a point - it's difficult to filter out spammers whose email addresses end
up looking like "[EMAIL PROTECTED]" just using people alone. Thankfully
subject filtering on 'Make money fast' with case insensitive fuzzy matching
gets a lots of stupid posts. But rather than kill everything, I use Gnus
scoring to 'shade' messages according to likely relevance. Massive cross
posting gets major blatting, just to three newsgroups gets a minor
demotion. Lots of '$' signs gets a moderate demotion. All caps gets demoted a
little - lots of newbies still insist on posting messages like 'HELP!!!!!'
which doesn't help me design a more aggressive policy. I have filters which
look for messages which end in random numbers of more than four digits, as
those posts are often spammers trying to beat the spambots looking for
identical titles. And of course I promote the messages from people who have
helped me in the past, who provide good advice or are generally polite and
thoughtful in their postings. So even if someone whose postings I want to see
posts "MAKE MONEY FATS" (sic) their message will still appear, but somewhat
lower than usual. And finally there are different promotion and demotion rules
for different newsgroups, often based on subject heading - for example in a
'redhat.*' newsgroup there is no point matching on subjects with 'linux' in
the title, but it is more relevant in, say, sci.image.processing if you are
looking for help with Linux image processing problems.

You'll probably have to tell us anyway. See in a flat memory model there
is no such thing as a fax pointer. Linux uses a flat memory model.
