2.6.15-rc6: known regressions in the kernel Bugzilla

The following bugs in the kernel Bugzilla [1] contain regressions in 
2.6.15-rc compared to 2.6.14 with patches:
- #5632 forcedeth driver occasionally hangs
- #5758 x86_64: PANIC: early exception

The following bug in the kernel Bugzilla contains a regressions in 
2.6.15-rc without a patch:
- #5760 No sound with snd_intel8x0 & ALi M5455 chipset
        (kobject_register failed)

If we want people to test -rc kernels, we should also try hard to fix 
the regressions they report (even more if there are already patches 
for them)...

I've Cc'ed all people who might be able comment on one or more of these 
issues.

We put code in the kobjet to report when callers fail, due to problems
in them, and the kobject code is blamed...

Looks like a sound driver issue, nothing has changed in the kobject
code.

thanks,

Thanks for tracking this.  Although I fear it won't come to much.

But there is no relevant change in sound stuff between 2.6.15-rc4 and
rc6 (except for minor fix of OSS drivers).  If it really worked with
2.6.15-rc4, something else got broken.

Herbert's reply at the end of the thread explains that what the user
is doing, applying SNAT to IPSEC, has undefined results currently.

Using netfilter with IPSEC is known to be broken since the beginning
of our IPSEC implementation, and we plan to cure it in 2.6.16 with
some excellent work done by Patrick McHardy and Herbert Xu.

So just remove that from your list please, thanks.
