When I try to use aha152x_cs on any recent kernel, I get messages like (scsi2:4:0) cannot abort running or disconnected command (scsi2:4:0) cannot reset current device so I enabled lots of debugging (in 2.6.30) and get (end of message log): busy: unknown(seldo) SCSISEQ( ); SCSISIG(MESSAGE OUT); INTSTAT (lo); SSTAT( SELDO ); SSTAT( ); SXFRCTL0( CH1 ); SIGNAL( ATNI BSYI ); SELID (e7), STCNT (0), SSTAT2( SEMPTY ); SFCNT (0); SCSICNT (0), OFFCNT(0), SSTAT4( ); DMACNTRL0( 16BIT PIO READ INTEN ); DMASTAT( DFIFOEMP ) enabled interrupts ( ENPHASEMIS ENBUSFREE ENSCSIPERR ) (scsi2:4:0) (aha152x_abort:1111) locking (scsi2:4:0) (aha152x_abort:1111) locked (scsi2:4:0) (aha152x_abort:1129) unlocking (locked at aha152x_abort:1111) (scsi2:4:0) (aha152x_abort:1129) unlocked (scsi2:4:0) cannot abort running or disconnected command (scsi2:4:0) aha152x_device_reset(dfa82a40)<7>(scsi2:4:0) (show_queues:2952) locking (scsi2:4:0) (show_queues:2952) locked queue status: issue_SC: (scsi2:4:0) (show_queues:2956) unlocking (locked at show_queues:2952) (scsi2:4:0) (show_queues:2956) unlocked current_SC: scsi 2:0:4:0: dfa82a40: cmnd=(cdb[0]=0x12 12 00 00 00 24 00 ); request_bufflen=36; resid=36; phase |syncneg|; next=0x(null) disconnected_SC: busy: unknown(seldo) SCSISEQ( ); SCSISIG(MESSAGE OUT); INTSTAT (lo); SSTAT( SELDO ); SSTAT( ); SXFRCTL0( CH1 ); SIGNAL( ATNI BSYI ); SELID (e7), STCNT (0), SSTAT2( SEMPTY ); SFCNT (0); SCSICNT (0), OFFCNT(0), SSTAT4( ); DMACNTRL0( 16BIT PIO READ INTEN ); DMASTAT( DFIFOEMP ) enabled interrupts ( ENPHASEMIS ENBUSFREE ENSCSIPERR ) (scsi2:4:0) cannot reset current device (scsi2:4:0) (aha152x_bus_reset_host:1247) locking (scsi2:4:0) (aha152x_bus_reset_host:1247) locked scsi2: bus reset<7>(scsi2:4:0) (show_queues:2952) locking BUG: spinlock trylock failure on UP on CPU#0, scsi_eh_2/7012 lock: d6d97b94, .magic: dead4ead, .owner: scsi_eh_2/7012, .owner_cpu: 0 Pid: 7012, comm: scsi_eh_2 Not tainted 2.6.30 #7 Call Trace: [<c0439076>] ? printk+0xf/0x11 [<c0210f02>] spin_bug+0x75/0x80 [<c0210fad>] _raw_spin_trylock+0x36/0x3b [<c043b7b2>] _spin_lock_irqsave+0x29/0x55 [<e1acfc7a>] ? show_queues+0xbe/0x35b [aha152x_cs] [<e1acfc7a>] show_queues+0xbe/0x35b [aha152x_cs] [<e1ad02ba>] aha152x_bus_reset_host+0x136/0x295 [aha152x_cs] [<e1ad048a>] aha152x_bus_reset+0xc/0xe [aha152x_cs] [<c02ba6cc>] scsi_try_bus_reset+0x25/0xa0 [<c02bb251>] scsi_eh_ready_devs+0x2fa/0x4ad [<c02bb66a>] scsi_error_handler+0x1a7/0x32e [<c02bb4c3>] ? scsi_error_handler+0x0/0x32e [<c012c8a0>] kthread+0x42/0x67 [<c012c85e>] ? kthread+0x0/0x67 [<c0103053>] kernel_thread_helper+0x7/0x10 BUG: spinlock lockup on CPU#0, scsi_eh_2/7012, d6d97b94 Pid: 7012, comm: scsi_eh_2 Not tainted 2.6.30 #7 Call Trace: [<c0439076>] ? printk+0xf/0x11 [<c0211073>] _raw_spin_lock+0xc1/0xe4 [<c043b7ca>] _spin_lock_irqsave+0x41/0x55 [<e1acfc7a>] show_queues+0xbe/0x35b [aha152x_cs] [<e1ad02ba>] aha152x_bus_reset_host+0x136/0x295 [aha152x_cs] [<e1ad048a>] aha152x_bus_reset+0xc/0xe [aha152x_cs] [<c02ba6cc>] scsi_try_bus_reset+0x25/0xa0 [<c02bb251>] scsi_eh_ready_devs+0x2fa/0x4ad [<c02bb66a>] scsi_error_handler+0x1a7/0x32e [<c02bb4c3>] ? scsi_error_handler+0x0/0x32e [<c012c8a0>] kthread+0x42/0x67 [<c012c85e>] ? kthread+0x0/0x67 [<c0103053>] kernel_thread_helper+0x7/0x10 Does anyone successfully use aha152x_cs now? If not, maybe it should just be removed from the kernel tree. -- ~Randy LPC 2009, Sept. 23-25, Portland, Oregon http://linuxplumbersconf.org/2009/ -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
