Hello.
I'm experiencing two regressions in 3.8-rcX.
Regression:
(1) Console shows nothing, which makes it impossible to determine whether the system is working or not.
(2) SCSI_SYM53C8XX_2 cannot register IRQ, showing below messages upon load.
PCI: enabling device 0000:00:0c.0 (0100 -> 0103) sym0: <895a> rev 0x0 at pci 0000:00:0c.0 irq 27 sym0: No NVRAM, ID 7, Fast-40, LVD, parity checking sym0: request irq 27 failure sym0: giving up ...
While (1) was fixed by now, I can't bisect (2) since (1) is preventing (2) from printing messages.
Bisection result:
No problem until commit b1112249 "OMAPDSS: DISPC: cleanup lcd/digit enable/disable".
(1) was introduced by commit 07c9249f "ARM: 7554/1: VIC: use irq_domain_add_simple()".
(2) was introduced between commit 07c9249f "ARM: 7554/1: VIC: use irq_domain_add_simple()" and commit 5c49985c "Merge branch 'fixes' of git://git.linaro.org/people/rmk/linux-arm".
(1) was fixed by commit 5c49985c "Merge branch 'fixes' of git://git.linaro.org/people/rmk/linux-arm".
(2) is not yet fixed as of commit 5da1f88b "Merge tag 'usb-3.8-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb".
Environment:
Host is Ubuntu 12.04 on x86_32. Cross compiling with ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- using gcc-arm-linux-gnueabi 4:4.6.2-7 and booting with arch/arm/boot/zImage using qemu-system 1.0.50-2012.03-0ubuntu2.1 .
