May 5 10:29:24 pollux kernel: Unable to handle kernel NULL pointer dereference at virtual address 00000014 Thereafter, almost nothing on the system worked. This was within minutes of booting, and thus isn't the result of long-term corruption. The system is an Athlon on an Epox 8KTA3 (=VIA), with BIOS flashed up to 17-Apr-2001. The kernel is 2.4.4, compiled as a PIII (since I still can't get an Athlon kernel to boot on this machine.) The ksymoops is attached (to prevent wraps). ===== % cat /proc/version Linux version 2.4.4 (root@pollux.dioscuri) (gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)) #4 Sat Apr 28 19:54:44 GMT-6 2001 ===== % cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 6 model : 4 model name : AMD Athlon(tm) Processor stepping : 2 cpu MHz : 1202.769 cache size : 256 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 mmx fxsr syscall mmxext 3dnowext 3dnow bogomips : 2398.61 ===== % cat /proc/pci PCI devices found: Bus 0, device 0, function 0: Host bridge: VIA Technologies, Inc.
