I've just installed kernel 2.3.51 on my Acer Travelmate 330T laptop, and
works great, but with one major problem. When I boot up without my
external IDE CDROM, I get a lost interrupt during the partition check
phase of my hard drive, and the system is unable to mount the root
filesystem and boot.
If the IDE CDROM (shows up as hdc) is plugged in, the "lost interrupt"
comes write after
Partition check:
hda:
and it pauses a second, then everything works great. Even if I later
unplug the CDROM the hard drive works beautifully.
This is a rough transcription of what happens without the CDROM:
Uniform Multi-Platform E-IDE driver Revision: 6.30
ide: Assuming 40MHz system bus speed for PIO modes; override with
idebus=xx ALI15X3: IDE controller on
PCI bus 00 dev 78
ALI15X3: not 100% native mode: will probe irqs later
ide0: BM-DMA at 0x7090-0x7097, BIOS settings: hda:DMA, hdb:pio hda:
IBM-DBCA-204860, ATA DISK drive
ide2: ports already in use, skipping probe
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
hda: IBM-DBCA-204860, 4645MB w/420kB Cache, CHS=592/255/63, (U)DMA
Partition check:
hda: hda1 hda2 <ide_dmaproc: chipset supported ide_dma_lostirq func only
11 hda: lost interrupt
>
After which booting continues, except that it can't find my root
partition, and the boot fails.
Can anyone shed any light on why this might be happening and if/how it
can be fixed? I tried turning DMA off, trying it with and without the
ALI15x3 driver, and I've tried kernels 2.3.49 through 2.3.51 with no luck.
All the 2.2.x kernels seem to work great though.
I'm not on the list, so I'd appreciate a cc.
Thanks!
Eric
