Hi,
whenever I try to insert a PCMCIA card in the slot, I get the
following message:
% Interrupt storm detected on "irq9:"; throttling interrupt source
Then I can remove and insert back the card at will, I won't get any
message from the kernel any more.
My kernel configuration file contains:
% device cbb
% device pccard
% device cardbus
(BTW, can someone explain me what are the purpose of those devices ?
I can't really understand it from the manpage.)
Output from pciconf(8):
% cbb0 at pci6:1:0: class=0x060700 card=0x00661025 chip=0x8031104c rev=0x00 hdr=0x02
% vendor = 'Texas Instruments (TI)'
% class = bridge
% subclass = PCI-CardBus
And the corresponding piece of dmesg:
% cbb0: <TI6411 PCI-CardBus Bridge> mem 0xc8216000-0xc8216fff irq 10 at device 1.0 on pci6
% cardbus0: <CardBus bus> on cbb0
% pccard0: <16-bit PCCard bus> on cbb0
vmstat -i:
% interrupt total rate
% irq0: clk 1094497 998
% irq1: atkbd0 4725 4
% irq8: rtc 140217 127
% irq9: bge0 uhci2+ 59147 53
% irq11: iwi0 uhci0* 6444 5
% irq12: psm0 1719 1
% irq14: ata0 3576 3
% Total 1310325 1195
I tried to turn on debug sysctls, but it shows nothing more:
% hw.cardbus.debug: 1
% hw.cardbus.cis_debug: 1
% hw.pccard.debug: 1
% hw.pccard.cis_debug: 1
% hw.cbb.debug: 1
Any help will be welcome. Let me know if you need for informations,
such a full verbose dmesg or so.
Thank you.
Best regards,
