| |
Well, this is what I get for being on the cutting edge... :-(
I'm now running into problems where the machine will totally hang (no network, no SysRq, no nothin') regularly. The triggers seem to be running aviplay or mozilla.
Symptoms will be that I am running aviplay or mozilla, and the machine will suddenly hang and need to be hard-reset. I can trigger it 100% by telling aviplay to zoom 2x.
I finally managed to reproduce it while I was on a console (I telneted in from another machine, and ran aviplay on the X display that was on console 7 while the machine was displaying console 1) - the only message before the hang was "Trying to vfree() nonexistent vm area (d0992000)" - no Oops was shown.
Whenever this happens, the e2fsck step at reboot shows a "Entry 'core.XXXX' in <dir> (XXXXXX) had deleted/unused inode XXXXXX. CLEARED" message. The core file is always in whatever directory I was running the process that seems to cause the crash. It seems like either the core is a symptom of the underlying problem, or the process coredumping is causing the hang. The machine is an Athlon Thunderbird 900MHz with 256M of PC133 DRAM on an MSI K7T Turbo R motherboard. I am running 2.4.3-ac12 currently, 2.4.3-ac11 and 2.4.3-ac5 hung the same way at least once each before I started tracking this down. I am running Red Hat 7.1, and am using the XFree86-4.0.3 RPMs that come with RH71 with the CVS DRI trunk installed over it. The kernel was built with kgcc, a gcc-2.96 built kernel has the same problem.
Any ideas?
