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.
