2.6.19-rc1 boot failure--ops in mpu401_init?

2.6.19-rc1 boot failure--ops in mpu401_init?

[J. Bruce Fields]

A machine that booted fine under 2.6.18-rc6 is failing to boot with
2.6.19-rc1.  After commenting out infinite loop of "Spurious ACK"
messages from atkbd.c that were hiding the original OOPS, I see the an
oops at klist_del+0xd/0x50 with a stack like:

bus_remove_device+0x9f/0xc0
device_del+0x17a/0x1b0
platform_device_del+0x69/0x80
platform_device_unregister+0xd/0x20
alsa_card_mpu401_init+0x7a/0x90
init+0x7f/0x260
kernel_thread_helper+0x7/0x10

Unfortunately I can't actually see the top of the OOPS.  (And haven't
had any luck getting a serial console to work yet...)

I also probably won't have time to try a git-bisect in the next few
days, though I could try it eventually if it'd help.

Let me know of any other details that would be helpful.

Thanks for the report.  Problem is known and fixed in later releases.
See the LKML/alsa-devel thread "Driver core: Don't ignore error returns
from probing".

OK, thanks.--b.
