Booting with BUG() enabled, I get:
kernel BUG at buffer.c:2630!
The relevant section is:
2618 static int grow_buffers(kdev_t dev, unsigned long block, int size)
2619 {
2620 struct page * page;
2621 struct block_device *bdev;
2622 unsigned long index;
2623 int sizebits;
2624
2625 /* Size must be multiple of hard sectorsize */
2626 if (size & (get_hardsect_size(dev)-1))
2627 BUG();
2628 /* Size must be within 512 bytes and PAGE_SIZE */
2629 if (size < 512 || size > PAGE_SIZE)
2630 BUG();
My disks are partitioned/formatted as follows:
hda1 Boot Primary Linux ext2 49.36
hda2 Primary Linux XFS 10001.95
hda3 Primary Linux raid autodetect 10001.95
Pri/Log Free Space 20925.12
hdc1 Primary Linux ext2 49.36
hdc2 Primary Linux ext2 10001.95
hdc3 Primary Linux raid autodetect 10001.95
Pri/Log Free Space 20925.12
I.e. my hpfs disk is not connected at this time.
I have compiled-in support for:
CONFIG_VIDEO_PROC_FS=y
CONFIG_EXT3_FS=y
CONFIG_FAT_FS=y
CONFIG_MSDOS_FS=y
CONFIG_VFAT_FS=y
CONFIG_TMPFS=y
CONFIG_ISO9660_FS=y
CONFIG_ZISOFS=y
CONFIG_HPFS_FS=y
CONFIG_PROC_FS=y
CONFIG_DEVFS_FS=y
CONFIG_DEVPTS_FS=y
CONFIG_EXT2_FS=y
CONFIG_UDF_FS=y
CONFIG_XFS_FS=y
CONFIG_XFS_DMAPI=y
CONFIG_HAVE_XFS_DMAPI=y
CONFIG_NFS_FS=y
CONFIG_NFS_V3=y
CONFIG_NFSD=y
CONFIG_NFSD_V3=y
CONFIG_ZISOFS_FS=y
CONFIG_ZLIB_FS_INFLATE=y
CONFIG_USB_DEVICEFS=y
Disregarding hpfs for a moment:
I see this during boot with working and non-working kernels:
FAT: bogus logical sector size 0
FAT: bogus logical sector size 0
Not sure what the FAT code complains about, but it could possibly be the
two raid partitions (raid0/xfs).
Anything else I can provide? kdb appears to require a little bit of
rewiring/replugging. Got no response to keyboardwhacking when I hit the
kdb prompt. Don't know if my USB keyboard makse a difference, but it
probably does.... :-)
If you want kdb stuff, please provide a little roadmap.
