Subjectkernel panic - bug or Hardware ?
DateMon, 11 Feb 2002 14:39:27 +0100
Hello Alan,

i run a quad-cpu netserver (64MB parityRAM , 2x onboard Adaptec aic7870 SCSI adapter) under  Debian potato with 2.2.x kernel
without any problem , but had to compile 2.4.17 for getting my Promise-Fastrack66-controller to work .. and since i run on 2.4 i 
get strange kernel panic (totally random in time and action) with always the same trace.
For i really have no idea on kernel debugging, i hope that i am right listed here to find help

i also attached the relevant ksyms-enties

c0110154 t clear_IO_APIC
c01154e4 T sys_init_module
c0115ad4 T try_inc_mod_count

i am really sure that this could be a hardware problem , but i cant trace the malfunc. hardware or identify it .. 
i also ran a comlete memtest on the RAM without result .. 

thanks 4 help
