Hello vger,
I've recently installed Linux 2.2.13pre14 (compiled here) on a new
Dell "Workstation 220," a dual-pentium 533 mhz, and after a few
reboots and a hardware change (installing a second 3com NIC) noticed
that its io_apic.c doesn't recognize the apic version, which it sees
as 0x20:
printk("....... : IO APIC version: %04X\n", reg_01.version);
if ( (reg_01.version != 0x10) && /* oldest IO-APICs */
(reg_01.version != 0x11) && /* Pentium/Pro IO-APICs */
(reg_01.version != 0x13) /* Xeon IO-APICs */
)
UNEXPECTED_IO_APIC();
I don't know whether it had been reporting that all along, or only
started after I added the second NIC (but I suspect the former).
Below is the boot log up to the point where INIT starts, in case the
context helps; if you want to see more let me know.
I've also copied from /proc the cpuinfo, interrupts, ioports, devices,
and pci files, in case any of that might be helpful. (Sorry, I
don't understand the hardware well enough to guess too well.)
Also I notice Linux isn't recognizing the second CPU, but I know that
it did earlier -- I haven't looked into that yet; if that could be
related to the unrecognized APIC, please let me know. Thanks.
