Description of problem: I apologize ahead of time for an annoyingly vague report. However: I have a dual Athlon system with Tyan S2469UGN moherboard, the version which includes integrated SCSI. This system has been completely stable under Fedora Core 4 since installation some months ago. However, the recent update to kernel 2.6.14-1.1644_FC4smp seems to have introduced some instability in the aic79xx driver. Version-Release number of selected component (if applicable): 2.6.14-1.1644_FC4smp How reproducible: Always Steps to Reproduce: 1. Install kernel 2.6.14-1.1644_FC4smp on system. Boot. 2. Use system for a while. Actual results: The system locks up with the following error in /var/log/messages repeated multiple times: Nov 30 08:57:54 apollo kernel: >>>>>>>>>>>>>>>>>> Dump Card State Begins <<<<<<<<<<<<<<<<< Nov 30 08:57:54 apollo kernel: scsi0: Dumping Card State at program address 0x95 Mode 0x22 Nov 30 08:57:54 apollo kernel: Card was paused Nov 30 08:57:54 apollo kernel: HS_MAILBOX[0x0] INTCTL[0x80] SEQINTSTAT[0x0] SAVED_MODE[0x11] Nov 30 08:57:54 apollo kernel: DFFSTAT[0x31] SCSISIGI[0x0] SCSIPHASE[0x0] SCSIBUS[0x0] Nov 30 08:57:54 apollo kernel: LASTPHASE[0x1] SCSISEQ0[0x0] SCSISEQ1[0x12] SEQCTL0[0x10] Nov 30 08:57:54 apollo kernel: SEQINTCTL[0x80] SEQ_FLAGS[0x0] SEQ_FLAGS2[0x0] Nov 30 08:57:54 apollo kernel: SSTAT0[0x0] SSTAT1[0x8] SSTAT2[0x0] SSTAT3[0x0] Nov 30 08:57:41 apollo apcupsd[2198]: NIS server startup succeeded Nov 30 08:57:57 apollo kernel: PERRDIAG[0x8] SIMODE1[0xa4] LQISTAT0[0x0] LQISTAT1[0x0] Nov 30 08:57:41 apollo apcupsd[2198]: apcupsd 3.10.18 (21 July 2005) redhat startup succeeded Nov 30 08:58:30 apollo kernel: LQISTAT2[0x0] LQOSTAT0[0x0] LQOSTAT1[0x0] LQOSTAT2[0x1] Nov 30 08:58:30 apollo kernel: Nov 30 08:58:31 apollo kernel: SCB Count = 8 CMDS_PENDING = 2 LASTSCB 0x3 CURRSCB 0x3 NEXTSCB 0xff40 Nov 30 08:58:31 apollo kernel: qinstart = 12587 qinfifonext = 12587 Nov 30 08:58:31 apollo kernel: QINFIFO: Nov 30 08:58:31 apollo kernel: WAITING_TID_QUEUES: Nov 30 08:58:31 apollo kernel: Pending list: Nov 30 08:58:31 apollo kernel: 4 FIFO_USE[0x0] SCB_CONTROL[0x60] SCB_SCSIID[0x7] Nov 30 08:58:31 apollo kernel: 7 FIFO_USE[0x0] SCB_CONTROL[0x60] SCB_SCSIID[0x7] Nov 30 08:58:31 apollo kernel: Total 2 Nov 30 08:58:31 apollo kernel: Kernel Free SCB list: 3 5 1 0 2 6 Nov 30 08:58:31 apollo kernel: Sequencer Complete DMA-inprog list: Nov 30 08:58:31 apollo kernel: Sequencer Complete list: Nov 30 08:58:31 apollo kernel: Sequencer DMA-Up and Complete list: Nov 30 08:58:31 apollo kernel: Nov 30 08:58:31 apollo kernel: scsi0: FIFO0 Free, LONGJMP == 0x80ff, SCB 0x7 Nov 30 08:58:31 apollo kernel: SEQIMODE[0x3f] SEQINTSRC[0x0] DFCNTRL[0x0] DFSTATUS[0x89] Nov 30 08:58:31 apollo kernel: SG_CACHE_SHADOW[0x2] SG_STATE[0x0] DFFSXFRCTL[0x0] Nov 30 08:58:31 apollo kernel: SOFFCNT[0x0] MDFFSTAT[0x5] SHADDR = 0x00, SHCNT = 0x0 Nov 30 08:58:31 apollo kernel: HADDR = 0x00, HCNT = 0x0 CCSGCTL[0x10] Nov 30 08:58:31 apollo kernel: scsi0: FIFO1 Free, LONGJMP == 0x8277, SCB 0x3 Nov 30 08:58:31 apollo kernel: SEQIMODE[0x3f] SEQINTSRC[0x0] DFCNTRL[0x4] DFSTATUS[0x89] Nov 30 08:58:31 apollo kernel: SG_CACHE_SHADOW[0x2] SG_STATE[0x0] DFFSXFRCTL[0x0] Nov 30 08:58:31 apollo kernel: SOFFCNT[0x0] MDFFSTAT[0x5] SHADDR = 0x00, SHCNT = 0x0 Nov 30 08:58:31 apollo kernel: HADDR = 0x00, HCNT = 0x0 CCSGCTL[0x10] Nov 30 08:58:32 apollo kernel: LQIN: 0x55 0x0 0x0 0x3 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 Nov 30 08:58:32 apollo kernel: scsi0: LQISTATE = 0x0, LQOSTATE = 0x0, OPTIONMODE = 0x42 Nov 30 08:58:32 apollo kernel: scsi0: OS_SPACE_CNT = 0x20 MAXCMDCNT = 0x1 Nov 30 08:58:32 apollo kernel: SIMODE0[0xc] Nov 30 08:58:32 apollo kernel: CCSCBCTL[0x0] Nov 30 08:58:32 apollo kernel: scsi0: REG0 == 0x3, SINDEX = 0x122, DINDEX = 0x104 Nov 30 08:58:32 apollo kernel: scsi0: SCBPTR == 0x3, SCB_NEXT == 0xff00, SCB_NEXT2 == 0xff86 Nov 30 08:58:32 apollo kernel: CDB 2a 0 4 80 8 9c Nov 30 08:58:32 apollo kernel: STACK: 0x29 0x15 0x125 0x125 0x0 0x257 0x25e 0x240 Nov 30 08:58:32 apollo kernel: <<<<<<<<<<<<<<<<< Dump Card State Ends >>>>>>>>>>>>>>>>>> Expected results: Stable system. Additional info:
This is a mass-update to all currently open kernel bugs. A new kernel update has been released (Version: 2.6.15-1.1830_FC4) based upon a new upstream kernel release. Please retest against this new kernel, as a large number of patches go into each upstream release, possibly including changes that may address this problem. This bug has been placed in NEEDINFO_REPORTER state. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed. Should this bug still be relevant after this period, the reporter can reopen the bug at any time. Any other users on the Cc: list of this bug can request that the bug be reopened by adding a comment to the bug. If this bug is a problem preventing you from installing the release this version is filed against, please see bug 169613. Thank you.
As of this writing, I've been running 2.6.15-1.1830 on the problem system for 18 hours. A backup has been run, which I've found in the past stresses the SCSI subsystem pretty well (SCSI system and user disks backing up to a SCSI tape drive). So far, no problems, so I'm marking this bug as fixed in the current release.
