Subject: 2.4.21-rc7 hang on boot after spurious 8259A interrupt: IRQ15.
Date: Fri, 13 Jun 2003 11:36:36 +0800 [thread overview]
Message-ID: <200306130958.39707.mflt1@micrologica.com.hk> (raw)
Doing swsusp testing in endless loop. On a P4/2.4G (ACPI=off)
on 192nd boot:
spurious 8259A interrupt: IRQ15.
Calibrating delay loop...
hang
Hit Reset and it rebooted OK
This is the first spurious 8259A interrupt: IRQ15 seen.
I see spurious 8259A interrupt: IRQ7 quite frequently on
varying hardware on both 2.4 and 2.5.
By design, the 8259A delivers a vector 7 when the IRQ
line is deasserted before the IRQ is serviced. This
applies to both edge and level trigger modes. A floating
"wire" or crapy chipset can pickup noise, but the driver
should handle it.
No problems seen with mainboard/cpu/ram in three months.
I dont' think it is HW, but it could be.
Also, spurious 8259A interrupts are quite recent, could
something be wrong with recent 8259A driver?
Regards
Michael

My current linux related activities in rough order of priority:
- Testing of 2.4/2.5 kernel interactivity
- Testing of Swsusp for 2.4
- Testing of Opera 7.11 emphasizing interactivity
- Research of NFS i/o errors during transfer 2.4>2.5
- Learning 2.5 series kernel debugging with kgdb - it's in the -mm tree
- Studying 2.5 series serial and ide drivers, ACPI, S3
