Jun 8 12:43:49 (none) user.alert kernel: Fixing recursive fault but reboot is needed!

Just tried upgrading to 0.23 hoping to remove some minor bugs in 0.22. I use another PC (IBM xSeries x345 server) as the backend/PXE/DHCP/SAMBA therefore I haven't lost anything on the previous system which is how up and running. The system starts up via PXE with no problem, sometimes I'll get into the front-end then at some point will fall back to terminal/bash. I've tried increasing the RAM available to 256M for the Ram drive but made no difference. I've also tried the newer version of minimyth 0.23-1.77 and the same thing occurs. Any help/suggestions on getting this to work?

Thanks
Long time user of minimyth
Wayne.

I've also doubled the amount of ram from 512M to 1G and it still fails.

Thanks
Wayne

I think 1GB of RAM may be a bit tight for the recent MiniMyth builds. Especially if part of that RAM is assigned to an on-board graphics adapter. If possible try to add at least another 512MB or get 2GB total. I had to add RAM memory when I found that Mythfrontend would run fine, but mplayer could not be started. It turned out that there was no memory left for mplayer to run. That was on 1GB. Adding another 1GB solved it for me. Maybe 256MB would have sufficed too back then, but I happened to have a spare stick of 1GB anyway.

Hmmm, I'll give it a go, however I not sure were I find 1G of DDR 333+ Ram. The GX60 only has 2 memory slots, but I'll try at work to see if I could borrow a couple of that size and see what happens.

Thanks for the advice
Wayne.

Ok, I cannot find what is causing the problem, this alone is stopping me from upgrading to the newer version of mythtv. Can anybody help? The machine in question is a GX-60 Dell computer based on intel chipset running a 2.2 Ghz processor. I'm still running 0.22-72 as this version is the only one which appears to function correctly.

What I've tried.

1. Increased the memory from 512M to 1024M, still occurs
2. NFS swap File.
3. Installed a hdd with a 1G swap partition, changed minimyth.pm to suit and appears in meminfo as 1G.
4. Run memory checking software from a LiveCD of siltaz and ubuntu - no problems there.

After a check of the memory it is not using the swap files therefore it appears to have enough. I've also tried installing minimyth onto a HDD and running from there - no diff and still produces this error. However O have had some luck in running the software. Even though this error occurs the minimyth, this install is still currently working

Just noticed, that I lose keyboard and remote (LIRC) control at random times. This then requires a restart to gain control back. Removing and reconecting the keyboard does not help at all. The machine will also not listen to the power button being pushed. If its playing a movie it will continue to do so. When the movie finishes I regain remote and keyboard control. This is occuring on all the gx-60s that i have. About 4 of them.

Cheers
Wayne.
