Hello, Poul-Henning. You wrote 7 =E0=EF=F0=E5=EB=FF 2013 =E3., 23:31:50: >> It looks like it picks up IRQ hint from ACPI, and, according to >> dmesg, it does so correctly, but after that it doesn't work :( PHK> So does the interrupt actually arrive ? vmstat -i interrupt total rate irq3: uart0 uart2 1 0 It doesn't look so. And uart1 and uart3 doesn't have interrupt according to `vmstat -i' (but share irq4 according to boot messages). PHK> If not: Interrupt routing issue ? How could I debug this? --=20 // Black Lion AKA Lev Serebryakov <lev@FreeBSD.org>
