Hi there, I'm having all kinds of odd issues IDE on these VIA chipsets (VIA C3 mini-itx machines). After a certain amount of time (goes from one hour to a month) the harddrive (or the whole ide subsystem?) will go nuts with the following messages, which I've finally managed to capture through a serial console. The machine doesn't hardlock but it's impossible to launch any command or reboot the machine remotely. I've even tried with "ide0=serialize ide1=serialize", since I read on this list that these options would cure most of the obscure IDE setups, but the problem still persists. I've reproduced this problem with all of the 2.4.2[4-8] series and also with 2.6.3 (which is the only one I tried some time ago). I attach the error messages, lspci and lsmod (kernel is compiled with CONFIG_BLK_DEV_VIA82CXXX=y). - Error messages: hdc: dma_timer_expiry: dma status == 0x20 hdc: timeout waiting for DMA hdc: timeout waiting for DMA hdc: (__ide_dma_test_irq) called while not waiting hdc: status timeout: status=0xd0 { Busy } hdc: drive not ready for command ide1: reset timed-out, status=0xd0 hdc: status timeout: status=0xd0 { Busy } hdc: drive not ready for command ide1: reset timed-out, status=0xd0 end_request: I/O error, dev 16:07 (hdc), sector 12845088 end_request: I/O error, dev 16:07 (hdc), sector 13369384 end_request: I/O error, dev 16:07 (hdc), sector 14155808 end_request: I/O error, dev 16:07 (hdc), sector 14417960 end_request: I/O error, dev 16:07 (hdc), sector 14942240 end_request: I/O error, dev 16:07 (hdc), sector 14942248 end_request: I/O error, dev 16:07 (hdc), sector 15204392 end_request: I/O error, dev 16:07 (hdc), sector 15466536 end_request: I/O error, dev 16:07 (hdc), sector 16252968 end_request: I/O error, dev 16:07 (hdc), sector 19472 end_request: I/O error, dev 16:07 (hdc), sector 19480 end_request: I/O error, dev 16:07 (hdc), sector 14942240 EXT3-fs error (device ide1(22,7)): ext3_get_inode_loc: unable to read inode block - inode=928422, block=1867780 end_request: I/O error, dev 16:07 (hdc), sector 0 end_request: I/O error, dev 16:07 (hdc), sector 19488 EXT3-fs error (device ide1(22,7)) in ext3_reserve_inode_write: IO failure end_request: I/O error, dev 16:07 (hdc), sector 0 end_request: I/O error, dev 16:07 (hdc), sector 14155808 EXT3-fs error (device ide1(22,7)): ext3_get_inode_loc: unable to read inode block - inode=879555, block=1769476 end_request: I/O error, dev 16:07 (hdc), sector 0 EXT3-fs error (device ide1(22,7)) in ext3_reserve_inode_write: IO failure end_request: I/O error, dev 16:07 (hdc), sector 0 end_request: I/O error, dev 16:07 (hdc), sector 270256 end_request: I/O error, dev 16:07 (hdc), sector 20616 end_request: I/O error, dev 16:07 (hdc), sector 20624 end_request: I/O error, dev 16:07 (hdc), sector 20632 end_request: I/O error, dev 16:07 (hdc), sector 20640 end_request: I/O error, dev 16:07 (hdc), sector 20648 journal_bmap_R65dbd63b: journal block not found at offset 2060 on ide1(22,7) Aborting journal on device ide1(22,7). end_request: I/O error, dev 16:07 (hdc), sector 4144 end_request: I/O error, dev 16:07 (hdc), sector 0 end_request: I/O error, dev 16:07 (hdc), sector 8 end_request: I/O error, dev 16:07 (hdc), sector 262168 ext3_abort called.

Thanks for any hints on how to debug further this problem. John ps.
