I found that none of my cardbus peripherals would work. The relevant lines from a dmesg output were: ACPI: PCI Interrupt 0000:00:0a.0[A] -> Link [LNKA] -> GSI 11 (level, low) -> IRQ 11 ACPI: PCI interrupt for device 0000:00:0a.0 disabled yenta_cardbus: probe of 0000:00:0a.0 failed with error -12 I used 'git bisect' to localize the problem, which turned out to be the changes in commit b408cbc704352eccee301e1103b23203ba1c3a0e, which was made on March 23. When I revert this patch, my cardbus system behaves normally and the cardbus controller initialization is ACPI: PCI Interrupt 0000:00:0a.0[A] -> Link [LNKA] -> GSI 11 (level, low) -> IRQ 11 Yenta: CardBus bridge found at 0000:00:0a.0 [103c:0022] Yenta O2: res at 0x94/0xD4: 00/ea Yenta O2: enabling read prefetch/write burst Yenta: ISA IRQ mask 0x0038, PCI irq 11 Socket status: 30000821 The memory map at the beginning of the dmesg buffer is BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000009fc00 (usable) BIOS-e820: 000000000009fc00 - 00000000000a0000 (reserved) BIOS-e820: 00000000000e0000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 0000000023ff0000 (usable) BIOS-e820: 0000000023ff0000 - 0000000023ffffc0 (ACPI data) BIOS-e820: 0000000023ffffc0 - 0000000024000000 (ACPI NVS) BIOS-e820: 00000000fff80000 - 0000000100000000 (reserved) 575MB LOWMEM available.
