Hello all:
I used jfsutils-1.1.4 utility to format jfs system. And recompile kernel 2.6.6 to support jfs.
 
After 68 days running continuously(in my app, the disk access is very frequently), a smart error occured. when i login to system, execute "ls -lR" in a directory. The ls can list some subdirectorys, but in a subdirectory the ls command hang up.
 
using dmesg command, i saw a lot error messages:
ide0: unexpected interrupt, status=0xd0, count=218
ide0: reset: success hda: recal_intr: status=0x51 { DriveReady SeekComplete Error }
hda: recal_intr: error=0x04 { DriveStatusError }
hda: write_intr error1: nr_sectors=1, stat=0x51
hda: write_intr: status=0x51 { DriveReady SeekComplete Error }
hda: write_intr: error=0x04 { DriveStatusError }
hda: recal_intr: status=0x51 { DriveReady SeekComplete E
 
But after reboot the system, all is ok. Howerer just after one day, this situation occured again.
 
Who can't give me some tips?
