Re: Strange boot problems on amd64-current (6.99.40)

[Chavdar Ivanov <ci4ic4%gmail.com@localhost>]

I have sumilar problem - Ive discussed it earlier.


C/P from my earlier mail to this list:
...
root file system type: ffs
fatal protection fauilt in supervisor mode
trap type 4 code 0 rip ffffffff80511a2a cs 8 rflags 10246 cr2

.....

I've tried bisecting with no success. We've located the exact place of
the crash (Masao pointed to me, I sprinkled printfs in the code).

Still no idea what is the problem.

The funny thing is, with DEBUG and DIAGNOSTIC it works fine. And yes,
I also have autoconfigured RAID1 root - and another RAID5 array in
this system
