I just tried a top of tree i386 kernel under KVM, and found that it fails to boot with a hang during initialization, right after:

console [netcon0] enabled

netconsole: network logging started

Uniform Multi-Platform E-IDE driver

ide-floppy driver 1.00

Driver 'sd' needs updating - please use bus_type methods

However, simply reverting this commit caused a panic on boot (not entirely surprising.)

Config attached (applied with yes '' | make oldconfig).

However, simply reverting this commit caused a panic on boot (not entirely surprising.)

Actually, it is surprising. That patch takes the default arithmetic for calculating the disk size out of sd and uses a routine to do it more efficiently in lib/string_helpers.c

So there are two problems: Why does it panic on revert (could you post the oops) and what does kvm object to in string_get_size ... it's a fairly innocuous routine as I read it ... your symptoms sound like the for loop isn't terminating.

Here is the oops. Note that it does get well past the hang point before it crashes. It is 100% reproducible.

Looks like it's trying to print a zero. I made a diff to print out the raw numbers, and did indeed get zero.

Now, *why* it is printing a zero is another matter (as is why using ffz() instead of ilog2() there...). Some quick investigation showed that sdkp->capacity is a 32-bit quantity in this configuration, and shifting it left by 9 of course ends up with zero; being a virtual disk, it's an exact power of two.

Still, it is bad that string_get_size() hangs on passing zero.

The spinlock lockup is still happening, so I'm assuming it is an unrelated bug that was masked by the string_get_size issue.

Patch series will follow shortly.

PATCH 1/2 scsi: fix computation of the full size of the device

When computing the full size of the device, we need to cast sdkp->capacity before shifting, since in some configurations sector_t can be a 32-bit number.

Also, change ffz(~x) to the more idiomatic ilog2(x).

PATCH 2/2 string_get_size(): don't hang on zero; no decimals on exact

We would hang forever when passing a zero to string_get_size(). Furthermore, string_get_size() would produce decimals on a value small enough to be exact. Finally, a few formatting issues are inconsistent with standard SI style guidelines.

- If the value is less than the divisor, skip the entire rounding step. This prints out all small values including zero as integers, without decimals.
- Add a space between the value and the symbol for the unit, consistent with standard SI practice.
- Lower case k in kB since we are talking about powers of 10.
- Finally, change "int" to "unsigned int" in one place to shut up a gcc warning when compiling the code out-of-kernel for testing.

However, simply reverting this commit caused a panic on boot (not entirely surprising.)
Quoted 9 lines
Actually, it is surprising. That patch takes the default arithmetic for calculating the disk size out of sd and uses a routine to do it more efficiently in lib/string_helpers.c
So there are two problems: Why does it panic on revert (could you post the oops) and what does kvm object to in string_get_size ... it's a fairly innocuous routine as I read it ... your symptoms sound like the for loop isn't terminating.
Looks like it's trying to print a zero. I made a diff to print out the raw numbers, and did indeed get zero.
Now, *why* it is printing a zero is another matter (as is why using ffz() instead of ilog2() there...). Some quick investigation showed that sdkp->capacity is a 32-bit quantity in this configuration, and shifting it left by 9 of course ends up with zero; being a virtual disk, it's an exact power of two.

Quoted 6 lines

Still, it is bad that string_get_size() hangs on passing zero.
The spinlock lockup is still happening, so I'm assuming it is an unrelated bug that was masked by the string_get_size issue.
Patch series will follow shortly.

Does this fix it?
