Subject: Re: [2/2] 2.6.22-rc4: known regressions v3

Hi All,

They apear as soon as simpleinit starts up. Somtimes I get to a login 
prompt before seeing any. Other times, commands in the simpleinit rc 
script fail.

They do apear to be random. If a command failes, you re-run the command 
and it is OK. Commands seen to fail are basic (depmod, rm cat ..).

The test I did use the same binaries with both the OK and problem kernels 
so it is not a change to the application code, it is definatly a kernel 
issue.

Regards
 	Mark Fortescue.
