Hi, I'm porting linux(2.6.31.6) to the Wintegra WINHDP2 refrence
board. As a refrence I already have an old BSP from Wintegra based
on kernel 2.6.10. During the kernel start up process I receive following
error: Reserved instruction in kernel code[#1]: Cpu 0 $ 0 : 00000000 1000fc00 802be630 00000001 $ 4 : 802be670 802be674 ffffffff 802f4d4c $ 8 : 1000fc01 1000001f 00000001 0000002b $12 : 00000000 000001f5 07a0d380 00000000 $16 : 00000000 00000000 00000000 1000fc00 $20 : 802e9674 bd030f04 3e490000 00000a72 $24 : 00000008

3c1f8010 Disabling lock debugging due to kernel taint Kernel panic - not syncing: Attempted to kill the idle task! Does anybody know where is the problem? I suspect, that the problem is in my interrupt routine,
because I receive this error as soon as the tick timer start's up. Regards, Ales |
