Summary IRQ problems with APIC enabled on a Neptune chipset, Pentium 90 SMP. Description Since kernel 2.4.21-pre2, IRQ problems are present on my Pentium 90 SMP, wi= th APIC enabled. It works well with 2.4.20 with APIC enabled, or with newer kernels with "noapic" kernel option. This computer has a Neptune chipset. The following bug report is similar to this one : http://lkml.org/lkml/2003/8/8/193 On kernel 2.4.21-pre2, there is a kernel oops before this, with a "Dereferencing NULL pointer". On kernel 2.4.21-pre4, just after the floppy probing, there is a "keyboard: AT keyboard not present?(ed)" Since 2.4.21-pre5, the floppy interrupt problem appears. It can be reproduced all the time. The system hangs during SCSI cards probing. Keywords : APIC, SMP, IRQ, Neptune chipset Kernel version Kernels between 2.4.21-pre5 and 2.4.23-pre3 do have this problem. ---------------------------------------------------------------------------= ---- Here is the console log of the 2.4.23-pre3 bootup : Linux version 2.4.23-pre3 (compudj@compubox) (gcc version 3.2.3 (Debian)) #= 11 SMP Sun Sep 7 17:25:10 EDT 2003 BIOS-provided physical RAM map: BIOS-e801: 0000000000000000 - 000000000009f000 (usable) BIOS-e801: 0000000000100000 - 0000000006000000 (usable) 96MB LOWMEM available. found SMP MP-table at 000f5e40 hm, page 000f5000 reserved twice. hm, page 000f6000 reserved twice.
