Hello all, I've been experiencing some weird lockups with
1.2.x kernels, currently 1.2.5. I have a 3c509 card at io
0x320 irq 9. When it locks up, I'll see syslog messages like
Apr 16 18:29:56 koti linux: eth0: Infinite loop in interrupt, status ffff.
Apr 16 18:30:30 koti linux: eth0: Missed interrupt, status then ffff now ffff T
x ff Rx ffff.
Apr 16 18:36:37 koti linux: eth0: Missed interrupt, status then ffff now ffff T
x ff Rx ffff.
After seeing this "infinite loop in interrupt" message the only
way to return the system to sane state is reboot.
Should I try to put the 3c509 at irq15? Might irq9 cause
some weird side-effects for its special cascaded nature?
