Re: 2.6.39-rc5-git2 boot crashs

["werner" <w.landgraf@ru.ru>]

The problem that the computer crashs if zip, unzip or move 
a big file, started with -rc1

The problem with the secondary reset-resistent crashs 
after a primary and-of-boot or after-boot crash started 
with -rc3 or -rc4, at least I perceived it then, but it's 
possible that it occured also before, at least then I 
didn't note it

Now I see, that nor the syslog don't contain everything 
(this was also better with 2.6.38.4).  For example, 
currently aren't logged these crashs which currently 
occure during rtc0 initializing (in addition to the other 
crashs protocolled in the log files). Also, as you can see 
from my before-last message, with the screen foto of 
/dev/pts/0 w.r.t. boot_vga, this also don't appear in the 
log file which was added at the end of the same message.

For being -rc5 , that kernel is rather bad.  I hope you 
get through to correct it until -rc10
