I also have been keeping track of 5 or 6 other bug reports that look similar, with a Pentium 4 3GHz 800 MHz bus / 512kb of L2 cache see my bug report at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=627019 My Pentium D 3GHz 800 MHz bus / 1mb of L2 cache ( next generation) is not showing any of these issues ( yet). > > > > > > This sounds like there is some sort of > hardware fault, but I can't see > > > why it would only occur when using PAE.

I have had some success boot the 686-pae flavor by adding debug=3 or debug=4 to the linux commandline in grub-pc I also have compiled a vanilla (upstreams default config) linux-image-3.0-rc7 and it worked well for several days ( but still showing minor glitches at boot time) But, after the udev upgrade to 172-1 the upstream kernel started showing the same seg faults and other stuff the debian 686-pae flavor kernels since 2.6.39-rc3-686-pae (iirc) have been showing. I just upgraded to 3.0.0-1-686-pae and it took three reboots to get to a login screen. The hang point on the second boot attempt was waiting for dev to be fully populated ( which froze there, but I only waited a minute or two before I shut down than rebooted. Than the third time I still got a udevd seg fault, but it was not fatal this time and I'm able to login. I didn't upgrade the grub packages yet, holding for next time. > > > -- Cheers > Frank -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
