[expert] IRQ stuff

[Julio Matarranz]

I just moved from red hat 6.2 to mandrake 7.2... i guess for the better.   Red Hat did fine, I had no problems but I wanted to try the Madrake distrbution.   The problem s that after the installation i found out that both my ether and my soound card werent working any more.   When I try to configure my sound card (SounBlasterPCI 128), using sndconfig I get this error msg:   modprobe error                                               The following error occurred running the modprobe program:      /lib/modules/2.2.17-21mdk/misc/es1370.o: init_module: Device or resource busy  /lib/modules/2.2.17-21mdk/misc/es1370.o: insmod                 /lib/modules/2.2.17-21mdk/misc/es1370.o failed                  /lib/modules/2.2.17-21mdk/misc/es1370.o: insmod sound-slot-0 failed   This sounded a bit like irq problem, so I checked the config:   # lspci   00:0b.0 Ethernet controller: Lite-On Communications Inc LNE100TX (rev 20)  Subsystem: Kingston Technologies: Unknown device f002  Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-  Status: Cap- 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR-  Latency: 32  Interrupt: pin A routed to IRQ 0  Region 0: I/O ports at a400  Region 1: Memory at cf000000 (32-bit, non-prefetchable)   00:09.0 Multimedia audio controller: Ensoniq ES1370 [AudioPCI] (rev 01)  Subsystem: Unknown device 4942:4c4c  Control: I/O+ Mem- BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-  Status: Cap- 66Mhz- UDF- FastB2B- ParErr- DEVSEL=slow >TAbort- <TAbort-<MAbort- >SERR- <PERR-  Latency: 32 (3000ns min, 32000ns max)  Interrupt: pin A routed to IRQ 0  Region 0: I/O ports at b000   Both interfaces had irq 0... i guess theres something wrong in here. Every other interface is ok.   Lets see if the ether is working properly:   # ifconfig -a   eth0      Link encap:Ethernet  HWaddr 00:C0:F0:48:5F:BA            inet addr:xxx.xxx.xxx.xxx  Bcast:xxx.xxx.xxx.xxx  Mask:255.255.255.0           BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1           RX packets:0 errors:0 dropped:0 overruns:0 frame:0           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:100           Base address:0x8000   lo        Link encap:Local Loopback            inet addr:127.0.0.1  Mask:255.0.0.0           UP LOOPBACK RUNNING  MTU:3924  Metric:1           RX packets:0 errors:0 dropped:0 overruns:0 frame:0           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:0   The interface is properly configured but is not up. Lets put it up   # ifconfig eth0 up SIOCSIFFLAGS: Resource temporarily unavailable   Looking over the internet this error msg it seems to be a IRQ probl... but I cant find a workaround.   Physically changing the interface slot is no good....   Now here Im stuck!   I guess the problem is to do with the irq stuff but to be honest I dont know how to solve it.   Anyone has any idea?   Thanks   Julio
