Is this still a problem with recent kernels (2.6.24 or 2.6.25-rc2)? The situation appears improved with 2.6.24/2.6.25 compared to 2.6.16, but occasionally, on card insertion, I still get the error log as below (test machine is a Fujitsu P-1610)... <6>ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx <7>Probing IDE interface ide0... <6>cs: IO port probe 0x100-0x3af: clean. <6>cs: IO port probe 0x3e0-0x4ff: clean. <6>cs: IO port probe 0x820-0x8ff: clean. <6>cs: IO port probe 0xc00-0xcf7: clean. <6>cs: IO port probe 0xa00-0xaff: clean. <4>hda: CF500, CFA DISK drive <6>hdb: probing with STATUS(0x50) instead of ALTSTATUS(0x0a) <6>hdb: probing with STATUS(0x04) instead of ALTSTATUS(0x0a) <4>hdb: ^L^B^L^B^L^B^L^B^L^B^L^B^L^B^L^B^L^B^L^B^L^B^L^B^L^B^L^B^L^B^L^B^L^B^L^B^L^B^L, ATA DISK drive <4>ide0 at 0x3100-0x3107,0x310e on irq 3 <6>ide-cs: hda: Vpp = 0.0 <6>sdhci: SDHCI controller found at 0000:08:03.1 [1180:0822] (rev 13) <6>ACPI: PCI Interrupt 0000:08:03.1[B] -> GSI 17 (level, low) -> IRQ 17 <4>sdhc0:slot0: Will use DMA mode even though HW doesn't fully claim to support it. <6>mmc0: SDHCI at 0xf0200000 irq 17 DMA <6>hda: max request size: 128KiB <6>hda: 8060928 sectors (4127 MB) w/1KiB Cache, CHS=15744/16/32 <6> hda: hda1 <6>hdb: max request size: 512KiB <4>hdb: lost interrupt <4>hdb: lost interrupt <4>hdb: lost interrupt <4>hdb: lost interrupt <4>hdb: lost interrupt May 10 10:55:22 linux-khsr kernel: pccard: PCMCIA card inserted into slot 0 May 10 10:55:22 linux-khsr kernel: cs: memory probe 0xf0200000-0xf02fffff: excluding 0xf0200000-0xf020ffff May 10 10:55:22 linux-khsr kernel: pcmcia: registering new device pcmcia0.0 May 10 10:55:22 linux-khsr kernel: Uniform Multi-Platform E-IDE driver May 10 10:55:22 linux-khsr kernel: ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx May 10 10:55:22 linux-khsr kernel: Probing IDE interface ide0...

Most recent kernel where this bug did not occur: ? probably pre-2.6.0 Distribution: SuSE 10.1, Ubuntu 6.0.6 Hardware Environment: Muramasa CV-50 laptop, Ricoh RL5c476, Kingston 4GB Ultimate (100x) compact flash pccardctl ident for Kingston CF : product info : "M-Systems", "CF500", "", "" manfid : 0x000a, 0x0000 function : 4 (fixed disk) Problem Description: (insert Kingston 4GB compact flash) Jun 29 22:06:12 muramasa kernel: pccard: PCMCIA card inserted into slot 0 Jun 29 22:06:12 muramasa kernel: cs: memory probe 0xa0000000-0xa0ffffff: clean.

In the meantime, hde1 is not available to be mounted. Ejecting the CF card and re-inserting a different 512MB card does not help) Steps to reproduce: (insert 4GB Kingston compact flash into Muramasa CV-50) problem not reproduced with Sandisk 512 MB compact flash into same laptop. Problem can be 'fixed' as per http://lkml.org/lkml/2004/4/7/181 (Chuan-Kai Lin) by changing a section in ide-probe.c (actual_try_to_identify) to if ((a ^ s) & ~INDEX_STAT) { printk(KERN_INFO "%s: was going to probe with STATUS(0x%02x) instead of " "ALTSTATUS(0x%02x) - use non-intrusive probe instead\n", drive->name, s, a); /* was to handle ancient Seagate drives, broken interfaces. */ /* seems to break Muramasa and Kingston 4GB CF, so next line changed */ hd_status = IDE_ALTSTATUS_REG; /* was IDE_STATUS_REG */ } else { /* use non-intrusive polling */ hd_status = IDE_ALTSTATUS_REG; }
