2.6.20-rc3-mm1 BUG: at arch/i386/mm/highmem.c:52

From: Eric Buddington
Date: Mon Jan 08 2007 - 03:16:55 EST

Machine: Linux <...> 2.6.20-rc3-mm1 #2 Mon Jan 8 00:24:59 EST 2007 i686 unknown

In normal (light) use, I experienced a long (~20s?) freeze, and errors
regarding hdc appeared in dmesg, along with the BUG. SMART on hdc
doesn't report any errors except a bad SMART checksum (I think that
may have been there before). It may be a hardware problem, but I
figure the BUG is relevant anyway.

Anyway, here's the dmesg and SMART output:


hdc: status timeout: status=0xd0 { Busy }
ide: failed opcode was: unknown
hdc: no DRQ after issuing MULTWRITE_EXT
hda: status timeout: status=0xd0 { Busy }
ide: failed opcode was: unknown
hda: no DRQ after issuing MULTWRITE_EXT
ide0: reset: success
