Revision d6b58f89f7257c8099c2260e2bea042a917d6cdf authored by Mark Fasheh on 21 November 2008, 22:06:55 UTC, committed by Mark Fasheh on 01 December 2008, 22:46:58 UTC
We're panicing in ocfs2_read_blocks_sync() if a jbd-managed buffer is seen. At first glance, this seems ok but in reality it can happen. My test case was to just run 'exorcist'. A struct inode is being pushed out of memory but is then re-read at a later time, before the buffer has been checkpointed by jbd. This causes a BUG to be hit in ocfs2_read_blocks_sync().

tristate "Sound card support"
depends on HAS_IOMEM
help
If you have a sound card in your computer, i.e. if it can say more
than an occasional beep, say Y. Be sure to have all the information
about your sound card and its configuration down (I/O port,
interrupt and DMA channel), because you will be asked for it.
You want to read the Sound-HOWTO, available from
<http://www.tldp.org/docs.html#howto>. General information about
the modular sound system is contained in the files
<file:Documentation/sound/oss/Introduction>. The file
<file:Documentation/sound/oss/README.OSS> contains some slightly
outdated but still useful information as well. Newer sound
driver documentation is found in <file:Documentation/sound/alsa/*>.
If you have a PnP sound card and you want to configure it at boot
time using the ISA PnP tools (read
<http://www.roestock.demon.co.uk/isapnptools/>), then you need to
compile the sound card support as a module and load that module
after the PnP configuration is finished. To do this, choose M here
and read <file:Documentation/sound/oss/README.modules>; the module
will be called soundcore.

help
This is used to avoid config and link hard dependencies between the
sound subsystem and other function drivers completely unrelated to
sound although they're sharing the AC97 bus. Concerned drivers
should "select" this.
