Re: i386 MP default configuration support [EISA trap]

Am 29.05.2013 21:45, schrieb Felix Deichmann:

dmesg appended, the system seems stable, at least with the current
PCI cards.
I could now test with an Adaptec AHA-2740/42W EISA card instead of the AHA-2940 PCI card, and the kernel traps when SMP is enabled. :/
The trap occurs independently of the card configured as level- or edge-interrupting (below output is for edge-triggered, as can be seen from int11/irq 11). 
The machine boots fine with the EISA card when SMP is disabled.

How can I further assist in debugging this?
