That is a bad attitude IMHO - if everyone follows that example, it
means that 2.6 will _never_ progress.  We, as kernel, developers rely
completely on users running the thing to find any problems, so these
types of reports are invaluable.

Ico - isn't this the same device which we recently had problems with
on PCMCIA?

Pardon my ignorance but how does one do this? As a part of the config before compiling kernel or?

Also, any ideas on the odd behavior of the hdspmixer? (see my other post)

No, just set the environment variable like
	export LD_ASSUME_KERNEL=2.4.19
(better globally) and start jack.  That's all.

In this way, glibc chooses LinuxThreads instead of NPTL.

Not checked yet...  Did hdspmixer work on any versions correctly on
your system?

yes, every jack client needs to be started with this env var set [additionally to the jack server], too.. otherwise it's not sufficient..

flo

P.S.: so add

export LD_ASSUME_KERNEL=2.4.19

to your ~/.bashrc

or even to your ~/.profile
