Hi folks,
when booting pre5 I got a crc-error while uncompressing
the kernel this morning. (/usr/src/linux/lib/inflate.c:1166 AFAICS) Rebooting didn't trigger it again and it's the first time I ever saw it.

I've never had any SIG11 problems while compiling kernels so I wouldn't expect bad RAM. (Normal people probably run Seti@home,
I run "while make bzImage; do date >> /tmp/kcompile; make clean; done" ;-)

OTOH, it's not reproducable which seems an indicator for hardware trouble :-(

Does anybody have any ideas?

Hi,

I would suggest to increase the 8bit waitstates in the BIOS by +1 (or more). - you might have to increase the 16bit waitstates as well (or instead of the 8bit ones).

It cured such a problem for me: - A Intel Pentium PC that had run Netware 3.12 perfectly happily for years didn't boot up with a CRC error after installing RedHat 7.0 on it. - Increasing the 8bit waitstates from 1 to 2 cured the problem completely and the PC is rocksolid now. - The PC also ran Windows quite happily (I installed it after the trouble with Linux just to see if it would work - I was worried about the hardware having gone dodgy.)

Hope this helps.

Regards,

Anton
