Hi all, I have still IRQ-Problems on my machine which seem to be ACPI related (i.e. which don't occur without ACPI) but seem to have a different source than the last shutdown/reboot issue. The last working kernel is from May 22, after the new ACPI-Code no kernel boots with ACPI enabled any more. The core problem is the handling of IRQ 10 on my machine. This IRQ is marked as 'Legacy/ISA' in my BIOS-Settings and is used for my ISA "Teles S0/16.3"-ISDN-Card. With my old working kernel, things look as follows: FreeBSD 5.2-CURRENT #0: Sat May 22 13:01:03 CEST 2004 [...] pcib0: slot 7 INTD is routed to irq 11 pcib0: slot 7 INTD is routed to irq 11 pcib0: slot 7 INTC is routed to irq 12 pcib0: slot 9 INTA is routed to irq 11 pcib0: slot 10 INTA is routed to irq 12 pcib0: slot 12 INTA is routed to irq 12 [...] sym0: <875> port 0xd800-0xd8ff mem 0xe3000000-0xe3000fff, 0xe3001000-0xe30010ff irq 11 at device 9.0 on pci0 [...] isic0 at port 0x580-0x59f,0x180-0x19f,0x980-0x99f,0xd80-0xd9f irq 10 flags 0x3 on isa0 Now, with newer kernels, there's a different IRQ-Routing, where "pcib0: slot 9 INTA is routed to irq 10" and therefore "isic0: Could not get IRQ for Teles S0/16.3" "sym0" is on IRQ 10 as well (of course), so the detection of my SCSI-Disks hangs (because of the ISA-Card on this IRQ I assume) and with this the whole boot process... :-( Obviously the new IRQ-Routing does not look at the BIOS-Settings and grabs an IRQ which is reserved for legacy ISA-Cards. I tried both possible "PnP-OS" settings but it makes no difference there. I admit that ISA cards aren't state of the art anymore, but in the moment it's my fastest Internet-access and it was working for a long time. I hope that this behaviour is not intended and that ISA-Cards remain to be supported under FreeBSD 5... -- Ciao/BSD - Matthias Matthias Schuendehuette <msch [at] snafu.de>, Berlin (Germany) PGP-Key at <pgp.mit.edu> and <wwwkeys.de.pgp.net> ID: 0xDDFB0A5F
